We recently finished our Ask the Expert discussion, "Incorporating recombinant proteins to produce blood-free media formulations for therapeutic cell types". During this Ask the Expert session, we discussed transitioning cells to blood free formulations, cell health and growth in blood-free medium and associated benefits.. Recent advancements in recombinant protein expression have enabled the cost-effective inclusion of recombinant proteins, such as albumin and transferrin in media formulations. These recombinant proteins can effectively replace human plasma or plasma-derived proteins and provide the benefit of reducing variability and risk of contamination from adventitious agents.. In this Ask the Expert session, Randall Alfano, Ph.D., Vice President of Product Development, provided insight on the use of recombinant albumin and transferrin to development blood-free media formulations for cell therapy production. InVitria has been successful in helping clinical development phase vaccine, stem, ...
Tissue culture. Dissociated mixed neocortical cell suspensions were prepared from fetal Swiss-Webster mice (gestational age 14-16 d) and plated on a previously established confluent layer of cortical astrocytes (see below) in 24-well tissue culture plates at 1-2 × 105 cells/cm2, generally as described previously (Rose et al., 1993). The initial plating medium was Eagles Minimum Essential Medium (MEM; Earles salts, supplied glutamine-free) supplemented with 10% heat-inactivated horse serum, 10% heat-inactivated fetal bovine serum, glutamine (total, 2 mm), and glucose (total, 21 mm). Cultures were kept in a 37°C/5% CO2 incubator. After 4-6 d in vitro, non-neuronal cell division was halted by exposure to 10−5 m cytosine arabinoside for 1-3 d. The cells were then shifted into a maintenance medium identical to the plating medium but lacking fetal serum. Subsequent media replacement occurred twice a week. Cultures were studied after 13-14 d in vitro.. Glial cultures were prepared using the same ...
Cell lines and culture conditions. Human breast cancer cell lines (MDA-MB-231 and MCF-7) and 293T were purchased from the American Type Culture Collection (ATCC). These cell lines were authenticated at ATCC before purchase by standard short tandem repeat DNA-typing methodology. The murine mammary carcinoma cell line E0771 was purchased from BeNa Culture Collection. The Py8119 cell line was provided by Suling Liu (Fudan University, Shanghai, China). The MDA-MB-231, E0771, and 293T cell lines were maintained in Dulbeccos modified Eagle medium (DMEM; Invitrogen) supplemented with 10% FBS (Invitrogen Corp.). The MCF-7 cell line was maintained in Eagles minimum essential medium (Invitrogen Corp.) supplemented with 10% FBS and 0.01 mg/ml human recombinant insulin. The Py8119 cell line was maintained in F12K nutrient media (HyClone) supplemented with 5% FBS. Each cell line was cultured in standard medium as recommended by ATCC. All cells were incubated at 37°C in a humidified incubator containing 5% ...
The effect has been studied of various media, hormones and of amino acids on the membrane potential of rat hepatoma cells in culture measured by microelectrode impalement. Cells in Eagles minimal essential medium plus 5% serum had a value which varied daily from about 5-8 mV, inside negative. The membrane potential of rat hepatocytes was measured to be 8.7 ± 0.2mV, inside negative. The membrane potential of the hepatoma cells was decreased by insulin and increased by glucagon. Membrane potential was unaffected by change of medium to Hanks or Earles balanced salt solutions or deprivation of serum. It was, however, reduced in cells in phosphate-buffered saline and by reduction of pH. The former effect was shown to be due to the higher [Na+] of phosphat-buffered saline as opposed to the other media. Addition of alanine, glycine, serine, proline and methylaminoisobutyrate all reduced membrane potential by 2-3 mV. Smaller decreases were seen with methionine, leucine and phenylalanine, but none ...
The effects of extracellular folate concentration on intracellular folate and phosphoribosylpyrophosphate (PRPP) levels and the cytotoxicity of methotrexate and 5-fluorouracil were studied in human KB cells grown in fetal bovine serum-supplemented Eagles minimum essential medium, which contained standard high folic acid levels (2.3 µm) (standard or S medium), or folic acid-free serum-supplemented medium containing approximately 4 nm 5-methyltetrahydrofolate (physiological or P medium), a folate level and form more comparable to that in normal human serum. Macrocytosis and prolongation of the doubling time by 150% were observed after 5-10 serial passes in P medium, but after 10-15 serial passes, KB cells became "adapted" to P medium with return of size and doubling time to values indistinguishable from cells maintained in S medium. Cellular folate levels fell, and marked elevations in PRPP levels from 68 ± 43 to 642 ± 287 pmol/mg cell protein (mean ± SD) were observed as KB cells were ...

In many cell culture applications using defined media for the in vitro cultivation of cells, the addition of supplemental nutrients and reagents is required. Additives such as antibiotics, buffers, and stains are frequently used to prevent bacterial contamination, control pH, and visibly monitor media conditions. Other supplements such as amino acids and vitamins are useful for enriched media beyond their normal concentrations. Attachment factors and transport factors are added to growth media to facilitate rapid cell propagation and enhance proper cell metabolism. Still other media supplements may be added to create conditions which will elicit specific cellular responses and effects, such as altered protein biosynthesis, accelerated antibody production and secretion, toxic response mechanisms, etc. ...
Shionogi carcinoma 115 (SC115) had been accepted for 20 years as an androgen-dependent mouse mammary tumor, the growth of which is stimulated only by androgen. However, we very recently found that the growth of SC115 tumors in vivo is stimulated not only by physiological doses of androgen but also by pharmacological doses of estrogen through the estrogen receptor system. In the present study, the growth-stimulative effect of estrogen on an androgen-dependent cloned cell line (SC-3) derived from SC115 cells, which showed androgen- and estrogen-dependent growth in vivo, was examined in vitro. In serum-supplemented medium (Eagles minimum essential medium containing 2% steroid-free fetal calf serum), testosterone or 5α-dihydrotestosterone (10-9-10-6 m) significantly stimulated the growth of SC-3 cells (3.2-fold increase in cell number at day 10 in culture containing 10-8 m androgens) and changed the shape of SC-3 cells from epithelial to spindle (fibroblast-like), whereas 17β-estradiol ...
The Film and Media Culture department is dedicated to the study of film and visual media as a vital aspect of a liberal arts education. Our students study film and a wide range of visual media, including television, digital games, online video, and video art, as aesthetic forms as well as in relation to the cultures that produced them.. While we are not a production-centered department or a traditional "film school," we fully integrate the creation and critical study of film and media in a manner appropriate to a liberal arts education. Students will balance the critical studies of film and media with the creation of media work, often within the same course.. The faculty in Film and Media Culture are active scholars and creators, writing books, creating videos, and contributing to the vibrant academic field of film and media studies. Our classes incorporate numerous screenings of films and media texts, with scheduled evening sessions and hands-on lab sections. We are housed in the new Axinn ...

Definition : Selective culture media in the form of liquids, solids, or semisolids used as a medium capable of supporting the growth of mycoplasma, while inhibiting the growth of other microorganisms. These selective culture media combine a rich nutritive base usually containing peptones, serum (e.g. horse serum, swine serum), growth factors favoring the growth of mycoplasmas and an antibiotic mixture inhibiting the growth of most antagonistic associated bacteria. Mycoplasma selective culture media are often used for the isolation and identification of mycoplasma in pharmaceutical products, especially in bulk vaccines, cell banks, and virus cultures..

Internet-Draft Content-Type Processing Model May 2009 1. Introduction The HTTP Content-Type header indicates the media type of an HTTP response. However, many HTTP servers supply a Content-Type that does not match the actual contents of the response. Historically, web browsers have been tolerated these servers by examining the content of HTTP responses in addition to the Content-Type header to determine the effective media type of the response. Without a clear specification of how to "sniff" the media type, each user agent implementor was forced to reverse engineer the behavior of the other user agents and to developed their own algorithm. These divergent algorithms have lead to a lack of interoperability between user agents and to security issues when the server intends an HTTP response to be interpreted as one media type but some user agents interpret the responses as another media type. These security issues are most severe when an "honest" server lets potentially malicious users upload files ...
Tryptic Soy Broth is widely used for the isolation of bacteria from clinical specimens, supporting the growth of a majority of pathogenic bacteria. This medium may be used for preparing dilutions of organism for colony counts, preparing standard inocula, and antibiotic sensitivity testing for both fastidious and non-fastidious microorganisms. Tryptic Soy Broth is also recommended for use in sterility testing for the detection of contamination with low incidence fungi and aerobic bacteria. (7) The concentration of ingredients in Tryptic Soy Broth, DS is critical to the media performance. When used to detect organisms in samples, the volume of sample being tested must be equal to the initial volume of TSB, DS. This will ensure that the ingredients in the media will be at the correct concentration after the addition of the test sample. Tryptic Soy Broth, also known as Soybean-Casein Digest, conforms to the formula given by the U.S. Pharmacopeia. (7) It was originally developed for testing the ...
In our initial experiments, dissociated cells were plated into dishes whose bottom was a glass coverslip. A styryl dye stained cells and adsorbed to the glass coverslip. Unbinding of the dye from the coverslip was very slow. Quantitative measurement of vesicle cycling was difficult when images were contaminated by a large background signal. Fortunately, unbinding of the dye was much faster when cells were plated onto a coverslip that had been coated with a thin layer of silicone plastic (Sylgard 184; Dow Corning, Midland, MI). Cells adhered to the silicone plastic if it was first covered with 0.25 mg ml−1 concanavalin A in 1 m NaCl for 20 min, rinsed with distilled water, and air dried.. The extracellular saline contained (in mm): NaCl, 120; KCl, 2.5; CaCl2, 0.2; MgCl2, 1; Na-pyruvate, 2; Na-lactate, 2; glucose, 10; and HEPES, 10; the pH was adjusted to 7.4 with NaOH, and the saline was supplemented with vitamins (1:100) and amino acids (1:100) formulated for Eagles minimum essential medium ...
p,With a previous observation of the defensive response against elevated temperatures and nutrient variation in ,em,Escherichia coli ,/em,in different culture media, present study further demonstrated the consequences of high temperature on the growth of ,em,Pseudomonas ,/em,spp. (SUBP01) ,em,Bacillus ,/em,spp. (SUBB01), and ,em,Salmonella ,/em,spp. (SUBS01). Bacterial growth was measured through the enumeration of the viable and culturable cells on Luria-Bertani (LB) and nutrient agar (NA) plates up to 72 hours, microscopic experiments were conducted to monitor subsequent physiological changes, and finally the loss of culturability due to high temperature stress was further confirmed by the observation of growth incapability through spot tests. A slight reduction in the culturable cells of ,em,Pseudomonas ,/em,spp. (SUBP01) was observed at 45°C after 24 to 72 hours of incubation in the LB media while no such inhibition of growth was noticed in the nutrient media.

The bacterial stressed state upon temperature raise has widely been observed especially in Escherichia coli cells. The current study extended such physiological investigation on Bacillus spp. SUBB01 under aeration at 100 rpm on different culture media along with the high temperature exposure at 48, 50, 52, 53 and 54 °C. Bacterial growth was determined through the enumeration of the viable and culturable cells; i.e., cells capable of producing the colony forming units on Luria-Bertani and nutrient agar plates up to 24 h. Microscopic experiments were conducted to scrutinize the successive physiological changes. Suppression of bacterial growth due to the elevated heat was further confirmed by the observation of non-viability through spot tests. As expected, a quick drop in both cell turbidity and colony forming units (~104) along with spores were observed after 12-24 h of incubation period, when cells were grown at 54 °C in both Luria-Bertani and nutrient broth and agar. The critical temperature (the
We studied the physiological response to limitation by diverse nutrients in batch and steady-state (chemostat) cultures of S. cerevisiae. We found that the global pattern of transcription in steady-state cultures in limiting phosphate or sulfate is essentially identical to that of batch cultures growing in the same medium just before the limiting nutrient is completely exhausted. The massive stress response and complete arrest of the cell cycle that occurs when nutrients are fully exhausted in batch cultures is not observed in the chemostat, indicating that the cells in the chemostat are "poor, not starving." Similar comparisons using leucine or uracil auxotrophs limited on leucine or uracil again showed patterns of gene expression in steady-state closely resembling those of corresponding batch cultures just before they exhaust the nutrient. Although there is also a strong stress response in the auxotrophic batch cultures, cell cycle arrest, if it occurs at all, is much less uniform. Many of the ...
In order to optimize culture conditions of bovine pulmonary endothelial cells (CPAE), we have compared different culture media, supports and extracellular matrices. Cell biomass was estimated by protein assay using Lowrys method. Different constituents including albumin, hydrocortisone, insulin, transferrin, triiodotyronine, Epidermal Growth Factor (EGF) and Fibroblast Growth Factor were separately added to Basal Defined Medium (BDM). Among them, BDM supplemented with EGF (1 ng/ml), hydrocortisone (100 nM), insulin (1 mu g/ml), triiodotyronine (2 nM) and linoleic acid complexed to albumin (10 mu g/ml) also named synthetic BDM appeared to be the best serum-free nutritive medium and showed similar results as compared to DMEM supplemented with 10% Fetal Bovine Serum (FBS). Several supports have then been tested including tissue culture polystyrene (as a reference), teflon, polycarbonate or poly(ethylene terephthalate) track-etched membranes. Among them, cells cultivated on surface treated ...
Objectives: The composition of nuclear membrane proteins (NMP) of fibroblasts derived from the periodontium is unknown. Identification of NMP is complicated since extraction of membrane proteins can be difficult due to the lipophilic nature of these molecules. The purpose of this study was to compare the quantity of unique identifiable membrane proteins using a single enzymatic wash preparation versus a two wash preparation for digestion and denaturation in proteomic analysis. Methods: GF used were obtained from 2 human biopsies derived from non-inflamed tissue in the retromolar pad area. Cells were cultured and propogated in Eagles minimal essential medium supplemented with 10% fetal bovine serum. GF were harvested when confluent in the 4th cell culture passage. NMP were isolated by differential centrifugation. 15 μg of protein from each sample was digested with trypsin or trypsin followed by a urea wash, followed by iTRAQ™ mass labeling for peptide qualitative and quantitative ...
A method for matching a query to a portion of media, includes receiving a query relating to media of interest and searching, based upon the query, an index of annotations. Each of the annotations represents a respective item of available media and includes a plurality of annotation values. Each of the plurality of annotation values represents a portion of the represented item of available media. By matching the query to an annotation value within the index, the start time of a media stream forming the portion of the item of available media represented by the identified annotation value can be identified. The identified media stream start time can then be provided in response to the query, allowing the appropriate portion of the applicable item of available media to be directly accessed.

b,This study proposed a methodology to evaluate the potential of mid-infrared (MIR) spectroscopy as a process analytical technology (PAT) tool for in situ (in-line) monitoring of cell culture media constituents, paving the way for on-line bioprocess monitoring and control of mammalian cell cultures. The methodology included a limit of detection (LOD) analysis and external influence investigation in addition to the calibration model development. The LOD analysis in the initial step provided a detailed procedure by which to evaluate the monitoring potential of the instrument of choice, for the application in question. The external influence study highlighted the potential difficulties when applying this technique to a typical mammalian cell culture. A comparative investigation between a fixed conduit immersion probe and flexible fiber-optic immersion probe was also carried out. Limitations associated with the use of MIR spectroscopy in the cell culture environment were also examined. A preliminary ...

The multipotency and anti-inflammatory effects of mesenchymal stem cells (MSCs) make them attractive for cell therapy in regenerative medicine. A large number of MSCs is required for efficient therapy owing to the low homing efficiency of MSCs to target sites. Furthermore, owing to limitations in obtaining sufficient amounts of MSCs, in vitro expansion of MSCs that preserves their differentiation and proliferative potential is essential. The animal factor included in culture media also limits clinical application. In this study, adipose-derived MSCs showed a significantly higher proliferation rate in STK2, a chemically-defined medium, than in DMEM/FBS. The expression of MSC surface markers was increased in the culture using STK2 compared to that using DMEM/FBS. Tri-lineage differentiation analyses showed that MSCs cultured in STK2 were superior to those cultured in DMEM/FBS. In addition, MSCs cultured in STK2 showed a reduced senescence rate, small and homogenous cell size, and were more genetically

Differential media are especially helpful when trying to identify a specific species. Bacteria can show widely different characteristics when grown in contact with various nutrients. A blood plate, one type of differential media, is often used to identify whether bacteria can digest blood cells. This is especially useful when diagnosing infection diseases. Streptococcus pneumoniae, a species that causes one type of pneumonia, can be identified partly thanks to its hemolytic activity, hemolysis being the breakdown of red blood cells. There are three different characteristic types of hemolysis that can be seen by growing bacteria on blood agar: alpha, beta, and gamma. Alpha hemolytic bacteria will only affect the medium that the colony is touching, turning the agar from red to green. Beta hemolytic bacteria cause a rather more dramatic change, removing the color from the media for some distance around each colony. Alpha hemolysis is only a partial digestion of the blood cells, while beta is a ...

Internet-Draft Media Type Registration June 2011 Note that this syntax is somewhat more restrictive than what is allowed by the ABNF in [RFC2045] and amended by [RFC2231]. There is no defined syntax for parameter values. Therefore registrations MUST specify parameter value syntax. Additionally, some transports impose restrictions on parameter value syntax, so care should be taken to limit the use of potentially problematic syntaxes; e.g., pure binary valued parameters, while permitted in some protocols, probably should be avoided. New parameters SHOULD NOT be defined as a way to introduce new functionality in types registered in the standards tree, although new parameters MAY be added to convey additional information that does not otherwise change existing functionality. An example of this would be a "revision" parameter to indicate a revision level of an external specification such as JPEG. Similar behavior is encouraged for media types registered in the vendor or personal trees but is not ...

A biological culture growth and observation system provides for the growth of a biological sample in a growth medium, and the observation of the grown sample (organism) through a microscope objective once growth is sufficient as to permit discrimination of the biological sample. Observation and growth is achieved in a single device. The system includes a tray with a top, and a sealable section on the top. Included within the tray is a depression, or well, that receives the growth medium to grow the biological organism in the well. A lid is sealable and resealable around the sealable section on the top of the tray. An interior side of the lid, that faces the growth medium, does not fog up in the presence of the growth medium. Optionally included is a barrier layer that is positioned over the well. The barrier layer minimizes evaporation from the growth medium and permits the biological culture growth and observation system to have a long shelf life.
Serum-Free media for cell cultures from Biological Industries include chemically-defined, protein-free, and serum-free media formulations for mammalian and stem cell cultures.
Cells that are grown in the Petri dish are indispensable tools in biomedical research. From cancer research to neurosciences, from immunology to virology: In all conceivable disciplines, scientists use cell cultures to examine, for example, the effects of new drugs, responses to signaling molecules, or the infectious behavior of pathogens. However, it is quite common that the cells that grow in the red culture medium are not what the researchers believe them to be. In the hustle of laboratory routine, it happens that tiny drops of culture medium are accidentally transferred from one container to another. If rapidly growing cells are introduced into other culture dishes in this way, they may swiftly outnumber other cells. Another critical issue is the permanent use of genetically variable cancer cells in laboratory experiments. These cells evolve over time by continuous mutations and after a while they no longer correspond to the initial cells. Frequently, however, the problem is simply caused by ...

Donor Horse Serum (DHS) is derived from healthy, live animals greater than 12 months of age. The donor animals receive regular veterinary inspection and care, and are kept in carefully managed and strictly segregated herds. The donor animals are all gelded draft horses in order to limit lot-to-lot hormone level variations A variety of cell types can be successfully propagated in DHS. It is frequently used in combination with bovine sera or independently to supplement media for mammalian cell culture. DHS is often utilized in bovine virus research applications since it does not contain bovine antibodies. It is also used as a supplement in some bacteriological media. Donor Horse Serum, Heat Inactivated is treated by heat inactivation where serum is exposed to a temperature of 56 °C for 30 minutes under controlled conditions. Learn more.

Hanna Rose Shell, a historian of science and technology, and a media maker, is an Associate Professor of Science, Technology and Society at MIT, and an affiliate in Comparative Media Studies. Shell will give a free talk titled, "Media Fabric: A History, Theory, and Practice of Textile Reuse.". Shell received a Ph.D. in the History of Science (Harvard, 2007) and an M.A. in American Studies (Yale University, 2002). In both her text and film-based scholarship, Shell studies the production, use, and transformation of often marginalized artifacts, located at the interstices of the found and the fabricated. Her current book project is a historical and theoretical investigation into the epistemology of reuse, in which objects of analysis include old clothes, decomposing vegetable matter, and other artifacts of strategic repurposing. Works from the last year include the scholarly article and media essay "Cinehistory and Experiments on Film," published in Journal of Visual Culture (Dec 2012) and the book ...

Media objects are transformed into active, connected objects via identifiers embedded into them or their containers. In the context of a users playback experience, a decoding process extracts the identifier from a media object and possibly additional context information and forwards it to a server. The server, in turn, maps the identifier to an action, such as returning metadata, re-directing the request to one or more other servers, requesting information from another server to identify the media object, etc. The linking process applies to broadcast objects as well as objects transmitted over networks in streaming and compressed file formats.

floating THP-1 cells - medium change advice - posted in Tissue and Cell Culture: Hello, I was adamantly asked to culture THP-1 cells and did so, by thawing a cryovial and seeding the cells in a 25 cm flask. 3 days later 99% of cells are floating, which I reckon is OK. Isnt it? So, do I need to change the medium before they reach ~8x 10^5 cells/ml and are ready to be passed? Since these are floating cells, how do I do that? Also, would a 1/3 split ratio be OK for these cells? Th...

In the creative brief, right under the media plan summary, there should be a description of each media property and the particularities of its audience. Which means theres a job for someone to do nothing but watch TV, read magazines, browse the web, and take lots of notes, sort of a mix between an account and media planners. After all, we have well-paid professionals hunting down and explaining obscure cultural phenomena - why not somebody who keeps track of the stuff thats popular today.

Over a two week period, eight prepared types of test media were provided to identify the assigned unknown mixed cultures. Not all of these tests were performed on every culture, as some were used only for gram positive or gram negative bacteria. The tests performed and what constituted a positive or negative test are as follows: Lab day 1; today in lab we obtained the unknown mixed culture "041"and one brain-heart infusion agar (BHIA). The first step was the preparation of the medium, the bottom of the BHIA dish was labeled with the bacterium number, initials, and section; then divided into four quadrants. The second step, we used the septic technique to transfer a small amount of culture with a flame-sterilized inoculating loop to the first quadrant, flamed and cooled the loop again then transferred a small amount of the culture from the first quadrant to the second using the quadrant streaking method as illustrated on page 18 of the lab manual, repeating this process until all four quadrants ...

This is the latest in a series of papers evaluating the efficacy of specific inositol stereoisomers to ameliorate phenotypes of Aβ pathology. It extends investigation of effects of Aβ oligomer-containing 7PA2 cell culture media on synaptic function into behavioral tasks in a rat infusion model. The observed effects appear to be due to blocking oligomers binding to neuronal membranes, which would directly affect toxicity while also improving the chances for clearance of small oligomers.. Importantly, the investigators measure and report dose-dependent levels of AZD-103 in CSF of rats who have had either 30, 100, or 300 mg/kg/day of AZD-103 added to their drinking water. The concentrations attained are 20-50 microM, well above the single-digit microM required to neutralize the effects of the infused 7PA2 cell media. This direct demonstration of AZD-103 bioavailability is often a difficult hurdle to overcome for putative therapeutics. Of course, the pharmacodynamics and pharmacokinetics remain to ...

Unparalleled performance - tested for optimal growth SUMMARY. CRITERION™ HardyCHROM™ Candida is a selective and differential medium containing chromogenic substrates. After degradation by specific enzymes, the substrates release different colored compounds. Certain species or groups of organisms can then be differentiated with a minimum number of confirmatory tests. Colonies of C. albicans appear green to dark metallic green, C. tropicalis colonies appear medium blue to dark metallic blue with a blue halo, and C. krusei colonies appear flat, often rough or crenated, and pink to medium pink in color. Other species appear pink, often with a darker mauve center (C. glabrata and other species). Other yeasts may appear white to pink. Additionally, HardyCHROM™ Candida can be used in conjunction with Rapid Trehalose Broth (Cat. no. Z205) or GlabrataQuick™ (Cat. no. Z298) to aid in the identification of C. glabrata. When HardyCHROM™ Candida is used as the primary plating medium, only colonies ...
Development of respiratory epithelium (RE) rudiment was studied in tissue culture after removal of mesenchyme (M) and respiratory tract (RT) in 13 days old embryos of A and C57BL mice. During long-term cultivation of intact RT, organotypic structures (branching bronchioles, alveolus-like cavities) developed. No epithelial organotypic structures developed in the presence of single M cells; explants were represented by layers of cubic epithelium. During long-term cultivation foci of atypical growth consisting of intensively proliferating basophilic cells with high nucleocytoplasmic ratio appeared in these explants. Regions of planocellular metaplasia with or without keratinization could be found in these foci. The frequency of atypical proliferates depended on the strain of donor mice and on the region of the explanted RT.. ...
