Naive B cell Naive B cell. A naïve B cell is a B cell that has not been exposed to an antigen. Once exposed to an antigen, the naïve B cell either becomes a memory B cell or a plasma cell that secretes antibodies specific to the antigen that was originally bound. Plasma cells do not last long in the circulation, this is in contrast to memory cells that last for very long periods of time.

Antigen-presenting cell An antigen-presenting cell (APC) or accessory cell is a cell that displays antigen complexed with major histocompatibility complexes (MHCs) on their surfaces; this process is known as antigen presentation. T cells may recognize these complexes using their T cell receptors (TCRs).

NK cell The form of cell composing many primitive unicellular organisms, such as bacteria. Prokaryotic cells do not have nuclei, which are partitioned by an intracellular membrane; instead the DNA forms one main coil in the cell cytoplasm.lara cell. A cuboidal epithelial cell found in the lining of the terminal and the respiratory bronchioles of the lungs. Clara cells are nonciliated, and they secrete surfactant, like the type II alveolar epithelial cells found deeper in the bronchial tree.

nerve cell 1. nerve cell-a cell that is specialized to conduct nerve impulses. neuron. gangliocyte, ganglion cell-a nerve cell whose body is outside the central nervous system; damage to ganglion cells in the retina may play a role in the development of glaucoma.erve cells typically consist of a cell body, which contains a nucleus and receives incoming nerve impulses, and an axon, which carries impulses away from the cell body. Also called neuron. See more at cell.

- Stem Cells as Vehicles for Gene Therapy. Stem cells can be classified as embryonic or adult, depending on their tissue of origin. The role of adult stem cells is to sustain an established repertoire of mature cell types in essentially steady-state numbers over the lifetime of the organism.ene therapy can be performed either by direct transfer of genes into the patient or by using living cells as vehicles to transport the genes of interest. Both modes have certain advantages and disadvantages. Direct gene transfer is particularly attractive because of its relative simplicity.

- To put this in simplistic terms, if we are to protect against the ravages of immune senescence, we need to increase our numbers of naive cells (virgin immune cells), while reducing numbers of surplus senile memory cells.

- A relatively recent breakthrough in stem cell research is the discovery that specialised adult cells can be ‘reprogrammed’ into cells that behave like embryonic stem cells, termed induced pluripotent stem cells (iPSCs). The generation of iPSCs has huge implications for disease research and drug development.

Somatic cell nuclear transfer The diagram depicts the removal of the donor nucleus for schematic purposes; in practice usually the whole donor cell is transferred. In genetics and developmental biology, somatic cell nuclear transfer (SCNT) is a laboratory strategy for creating a viable embryo from a body cell and an egg cell. The technique consists of taking an enucleated oocyte (egg cell) and implanting a donor nucleus from a somatic (body) cell.

LABORATORY OF MAMMALIAN CELL BIOLOGY AND DEVELOPMENT My laboratory uses mammalian skin as a model system to study adult stem cells. At the surface of our body, skin epidermis is readily accessible, and its stem cells can be cultured and passaged long-term without losing their stemness. Shortly after gastrulation, embryonic skin begins as a single layer of multipotent epithelial cells. These cells will give rise to the epidermis, and its appendages, which include hair follicles, sebaceous glands, sweat glands and even mammary glands.

What Causes Cancer? (Quiz 1) Create a free account to save it. A cell from which a variety of other cells can develop through the process of cellular differentiation. Stem cells can produce only a certain group of cells (as with skin stem cells) or any cell in the body (as with embryonic stem cells).
