By transducing two genes (c-MYC and BCL-XL) into iPS cells and ES cells, a research team has succeeded in producing erythrocyte progenitor cells with almost unlimited ability to replicate in vitro, which they then differentiated successfully into mature erythrocytes. (sciencedaily.com)
Erythrocytes are produced in the body by progressive evolution of hematopoietic stem cells into hematopoietic progenitor cells and then erythroblasts. (sciencedaily.com)
Hematopoietic progenitor cells, however, still have self-replication ability, and if the factors involved in this self-replication could be identified, it might become possible to induce virtually unlimited replication of progenitor cells. (sciencedaily.com)
The research showed that an increase in the expression of the c-MYC gene led to an enhancement of the replication ability of erythrocyte progenitor cells. (sciencedaily.com)
It was also found that the expression of the BCL-XL gene was higher during the maturation process of erythrocyte progenitor cells than during their replication process. (sciencedaily.com)
As the c-MYC gene and BCL-XL gene are present within erythrocyte progenitor cells, methods that make use of them actually mimic the body's own system and can therefore be thought of as safer with a view to future clinical application than the previously developed systems for large-scale erythrocyte production using oncogene-derived from Human papillomavirus that are not normally expressed in the human body.

First, we utilized single cell sequencing to dissect the differentiation of stem cells to midbrain dopaminergic neurons. (lu.se)

This study demonstrates the potential of V H H-based CAR T for pancreatic cancer therapy and provides an engineering strategy for developing potent CAR T cells targeting membrane-distal epitopes. (nature.com)
Viruses whose particles (virions) are surrounded by a lipid bilayer derived by budding from the cell membrane. (nationalacademies.org)
Yoda1, a specific PIEZO1 agonist, activates a small membrane current and thereby triggers β-cell electrical activity with resultant stimulation of Ca 2+ -influx and insulin secretion. (lu.se)
This paradox is resolved by our finding that PIEZO1 translocates from the plasmalemma into the nucleus (where it cannot influence the membrane potential of the β-cell) under experimental conditions emulating T2D (high glucose culture). (lu.se)

Heterogeneous antigen expression is a key barrier influencing the activity of chimeric antigen receptor (CAR) T cells in solid tumors. (nature.com)
In addition, embryonic stem cells may be modified by homologous recombination for use in producing chimeric or transgenic mammalian hosts, which may be used as source of universal donor organs. (justia.com)

Scientists have cloned organisms before, generally by injecting the nucleus of a donor cell into an egg whose own DNA has been removed. (livescience.com)

Furthermore, single-cell-based proteomic and transcriptomic analysis of D4-IgG4H-CD28TM CAR T cells reveals specific genes (e.g. (nature.com)
Because the nucleus includes the vast majority of the DNA present in the cell, this process means that the genes in that new egg come mostly from the mother, not the donor. (inverse.com)
However, a small percentage of genes in that DNA dwells outside the nucleus in organelles called mitochondria. (inverse.com)
The very important question to be addressed at that time was whether all cell types in the body have the same set of genes. (biologists.com)
The JAK2 , MPL , and THPO genes provide instructions for making proteins that promote the growth and division (proliferation) of blood cells. (medlineplus.gov)

Given the complexity of the biological function of mitochondria, researchers have begun to consider rescuing the injured cells through mitochondrial transfer, that is, replacing damaged mitochondria with healthy mitochondria from donor cells. (frontiersin.org)
Allen Institute for Cell Science researchers photograph thousands and thousands of different cells under the microscope. (alleninstitute.org)
The stem cells could be studied in the laboratory to help researchers understand what goes wrong in diseases like these. (eurostemcell.org)

However, an animal created through this technique would not be a precise genetic copy of the source of its nuclear DNA because each clone derives a small amount of its DNA from the mitochondria of the egg (which lie outside the nucleus) rather than from the donor of cell nucleus. (who.int)
CC (Carbon Copy), the first cat produced from a clone, was created from an ovarian cell taken from her genetic donor, Rainbow, a calico cat. (quizlet.com)

Biologists at the Allen Institute have further engineered these stem cells to tag certain proteins or cellular structures with glowing fluorescent labels. (alleninstitute.org)
During the final stages of maturation, lens cell organelles are dismantled, removing the machinery normally responsible for digesting and rebuilding proteins. (databasefootball.com)
c) Post tissue homogenization of the nucleus, the precipitate that contains the water-insoluble (WI) crystallin proteins is separated from the supernatant that contains the water-soluble (WS) by centrifugation. (databasefootball.com)
These proteins work together to turn on (activate) the JAK/STAT pathway, which promotes the proliferation of blood cells, particularly platelets and their precursor cells, megakaryocytes. (medlineplus.gov)

The abnormality in mitochondria of the aged donors was not attributable to either decrease in the copy number of mtDNA molecules or increase in the copy number of deletion mutant mtDNA molecules, but to significant decrease in overall polypeptide synthesis in the mitochondria. (nih.gov)

Yet, PIEZO1 expression is elevated in islets from human donors with type-2 diabetes (T2D) and a rodent T2D model (db/db mouse), in which insulin secretion is reduced. (lu.se)

A relatively small number of cells, however, do have the capacity to give rise to different kinds of cells. (lifeissues.net)
Multipotent mesenchymal stromal cells (MSCs), also known as mesenchymal stem cells, have the capacity to differentiate into a variety of cell types (Figure 1 ), including adipocytes, chondrocytes, and osteocytes [ 9 , 10 ]. (hindawi.com)

Notably, this study identified a potential biomarker for liver transplant donor graft quality. (jci.org)
Involved inflammatory cells produce cytokines and chemokines, and generate ROS, further contributing to graft dysfunction. (jci.org)
However, post-mortem analysis of transplanted tissue revealed accumulation of pathological Lewy bodies in a small subset of transplanted cells over time, revealing a host-to-graft disease propagation. (lu.se)
The advent of iPSCs has opened up the possibility to graft patient-specific cells which most likely would circumvent the need for immunosuppression. (lu.se)

Equine mesenchymal stem cells from bonemarrow, adipose tissue and umbilical cord:immunophenotypic characterization anddifferentiation potential. (sciendo.com)
Cryopreserved allogeneic mesenchymal stem cells enhance wound repair in full thickness skin wound model and cattle clinical teat injuries. (sciendo.com)
The normal process of fracture repair begins with an immediate inflammatory response as the innate immune system (macrophages, monocytes, neutrophils, and NK cells) responds with a variety of cytokines that recruit and activate several cell types, including osteoprogenitor mesenchymal stem cells (MSCs), to the site of injury [ 1 , 2 ]. (hindawi.com)

Those were spindle removal, donor cell fusion, and cytoplast activation. (news-medical.net)

The protective mechanism which protects the host from disease, as a result of invasion of viruses, bacteria, or other pathogens, is also able to recognize cells which come from a different mammalian host, even an allogeneic host. (justia.com)
To our knowledge, this is the first report of cloned mammalian offspring originating from nonviable cells. (cnrs.fr)

These cells have been sought after as potential therapies for diseases ranging from heart disease to Parkinson's to cancer. (news-medical.net)

Adipose stem cells in reparative goat mastitis mammary gland. (sciendo.com)

This triggered an increase in paracellular permeability via cellular redistribution of claudin 3 (CLDN3) from TJs into cell nuclei followed by disruption of epithelial integrity and formation of epithelial lesions. (springer.com)
