A process and apparatus for cell purification and ablation is disclosed. The present invention comprises a laser system which directs radiant energy at computer or manually selected individual cells thereby disrupting DNA, RNA and protein structure in those cells. The present invention produces a purified tissue section containing relatively intact DNA, RNA or protein from only the untreated cells. This purified sample is suitable for amplification of material by PCR or other techniques for the analysis of molecular genetic features in the selected cells of interest.
A sensitive and general technique has been devised for the dual purposes of cloning genes by using antibodies as probes and isolating unknown proteins encoded by cloned DNA. The method uses an expression vector, lambda gt11 (lac5 nin5 cI857 S100), that permits insertion of foreign DNA into the beta-galactosidase structural gene lacZ and promotes synthesis of hybrid proteins. Efficient screening of antigen-producing clones in lambda gt11 recombinant cDNA libraries is achieved through lysogeny of the phage library in hflA (high-frequency lysogeny) mutant cells of Escherichia coli; lysogens produce detectable quantities of antigen on induction, even when plated at high cell densities. The vector is also designed to facilitate the isolation of proteins specified by previously cloned gene sequences. Hybrid proteins encoded by recombinant phage accumulate in strains defective in protein degradation (lon mutants) in amounts amenable to large-scale purification. Antibodies produced against the portion ...

Atherosclerosis is a chronic inflammatory disease of the arterial wall characterized by lipid deposition, plaque formation, and immune cell infiltration. Innate and adaptive immune cells infiltrate the artery during development of the disease. Moreover, advanced disease leads to formation of artery tertiary lymphoid organs in the adventitia (Grabner et al., 2009; Hu et al., 2015). Various and diverse types of immune cells have been identified in the aorta adventitia vs atherosclerotic plaques (Elewa et al., 2016; Galkina et al., 2006; Lotzer et al., 2010; Mohanta et al., 2016; Mohanta et al., 2014; Moos et al., 2005; Srikakulapu et al., 2016; Zhao et al., 2004). There are conflicting reports on the number and subtypes of immune cells in the aorta depending on the age of the animals, the protocol that is used to obtain single cell suspensions, and the dietary conditions of the mice (Campbell et al., 2012; Clement et al., 2015; Galkina et al., 2006; Kyaw et al., 2012). The number of immune cells in the
Circulating tumor cells (CTCs) are shed from solid tumors and found at extremely low frequencies in the blood of patients in most cancers. A subset of these cells can seed and give rise to metastases, which is the primary cause of cancer-related mortality. Isolation and characterization of these cells from blood as a liquid biopsy can be a sensitive, non-invasive method for early detection, disease monitoring and therapy selection. CTCs can be found even at early disease stages in preclinical models and patients. There is increasing evidence that clusters of CTCs in blood are associated with higher metastatic potential; however, efficient isolation and interrogation of these rare clusters is challenging. In this study, we utilize an in-line rare cell enrichment platform developed by Becton Dickinson (BD), coupled with the BD FACSTM Influx cell sorter to rapidly isolate both single cells and clusters from blood. This platform utilizes magnetic particle-based depletion of unwanted leukocytes and ...

Current Research: Parturition (labor) is a sterile inflammatory event whereby maternal leukocytes invade the uterus and cervix. This is the process by which labor, both term and preterm, is instigated. Our lab is interested in two things: 1. What factors must be present in maternal blood for leukocytes to migrate to the lower uterus? 2. What changes occur on the surface of the leukocyte to enable it to respond to these factors? To that end, we collect blood from women in different stages of pregnancy, isolate leukocytes, and use a variety of different techniques in order to answer these questions. We draw blood, use confocal microscopy, RNA extraction and analysis, western blot, cell isolation protocols, cytokine analysis and flow cytometry. The goal of this lab is to understand how labor is instigated, and therefore contribute to knowledge that would help detect preterm birth in a blood test before it begins. By detecting preterm birth before it begins, patients at risk can be transported to ...

Microarray analysis and RNA-Seq are powerful tools for investigating differential gene expression in animal models of human genetic disease. Often, these models are loss of function mutations introduced by gene targeting or trapping. One difficulty in such experiments, especially where work on congenital malformations is concerned, is that whole embryo or regional dissections will commonly contain cells that do not express the gene of interest. Thus where cell autonomous effects are of primary interest, for example in the case of transcriptional regulators, such experiments will be compromised by dilutional effects and perhaps secondary effects on surrounding, non expressing tissues. Isolation of the relevant expressing lineage can mitigate these effects. Flow cytometry offers one route to cell purification but requires a fluorescent marker, and relatively few fluorescent protein gene reporters are available. FACS-Gal (1) offers the potential to capitalize upon the large existing repository of ...

Inowa et al. (15) recently reported the presence of an SP in a limited number of unfractionated normal human renal specimens which were uncharacterized due to the lack of tissue. Here, we present phenotypic and functional characterization of both normal and malignant human renal epithelial SP.. In this study, the overall cellular population was enriched for epithelial cells before SP analysis. This resulted in the isolation of a larger SP (3.8 ± 0.4 and 5.9 ± 0.9% for NK and RCC, respectively) than previously identified (15). This is in keeping with rodent studies in which embryonic and adult renal SP account for between 0.03 and 5.1% of the cells (14, 16). This variability could be explained by the differences in the isolation techniques and the well-known variability of SP due to different FACS conditions (20). The increased SP in malignant tissue is higher than that of other solid tumors such as prostate cancer, which shows a 2- to 10-fold reduction of SP cells in malignant tissue ...
