Epithelial cells ( which are non-circulating ) normally have active integrins at their cell membrane, helping maintain their stable adhesion to underlying stromal cells that provide signals to maintain normal functioning.

The growth of cervical loop cells into the deeper tissues forms Hertwig's Epithelial Root Sheath, which determines a tooth's root shape.

Epithelial cells of the lung and breast both contain keratin-7, but some other glandular epithelia, such as those of the colon and prostate, do not.

Epithelial cells are normally shed into the ventriculus where they burst – releasing digestive enzymes.

Epithelial cells, specifically type II pneumocytes, also internalize conidia which traffic to the lysosome where ingested conidia are destroyed.

The research used rat PC12 cells and Human Lens Epithelial ( HLE ) cells cultured for four hours on the surface modified porous silicon.

Epithelial tissue includes, but is not limited to, the surface layer of skin, glands and a variety of other tissue that lines the cavities and organs of the body.

The specific staining by both direct and indirect methods showed that WTV antigen was concentrated in the pseudophloem tissue and in a few thick-walled cells in the xylem region, but was not detectable in any other tissues of the root and stem tumors.

The egg is placed into a Petri dish where it develops into embryonic stem cells, which have shown potentials for treating several ailments.

Researchers have grown solid jawbones and tracheas from human stem cells towards this end.

In very severe myelosuppression, which occurs in some regimens, almost all the bone marrow stem cells ( cells that produce white and red blood cells ) are destroyed, meaning allogenic or autologous bone marrow cell transplants are necessary.

An understanding of the specialization of cells during embryogenesis has provided information on how stem cells specialize into specific tissues and organs.

The proliferating cells tend to be distinct from differentiated cells ( see stem cell and progenitor cell ).

But some stem cells migrate to where they are needed, such as mesenchymal stem cells which can migrate from the bone marrow to form e. g. muscle, bone or adipose tissue.

These pigs were bred to study human organ transplants, regenerating ocular photoreceptor cells ,, neuronal cells in the brain, regenerative medicine via stem cells, tissue engineering, and other diseases.

* Introduction to Genetic Engineering Covers general information on Genetic Engineering including cloning, stem cells and DNA.

in 1992 Doctor Claudio Bordignon working at the Vita-Salute San Raffaele University, Milan, Italy performed the first procedure of gene therapy using hematopoietic stem cells as vectors to deliver genes intended to correct hereditary diseases.

Blood was removed from Andrew's placenta and umbilical cord immediately after birth, containing stem cells.

Retroviruses and stem cells were mixed, after which they entered and inserted the gene into the stem cells ' chromosomes.

For four years T-cells ( white blood cells ), produced by stem cells, made ADA enzymes using the ADA gene.

This technology is of use, not only for research purposes, but also for clinical gene therapy aiming at the long-term correction of genetic defects, e. g., in stem and progenitor cells.

In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing adult tissues.

In the strictest sense, this requires stem cells to be either totipotent or pluripotent — to be able to give rise to any mature cell type, although multipotent or unipotent progenitor cells are sometimes referred to as stem cells.

A: stem cell ; B: progenitor cell ; C: differentiated cell ; 1: symmetric stem cell division ; 2: asymmetric stem cell division ; 3: progenitor division ; 4: terminal differentiation

Asymmetric division, on the other hand, produces only one stem cell and a progenitor cell with limited self-renewal potential.

Pluripotent stem cells undergo further specialization into multipotent progenitor cells that then give rise to functional cells.

Examples of stem and progenitor cells include:

As it turns out, epigenetic processes play a crucial role in regulating the decision to adopt a stem, progenitor, or mature cell fate.

To test this prediction, the authors conducted whole-genome profiling of DNA methylation patterns in several human embryonic stem cell ( ESC ), iPSC, and progenitor cell lines.

HSC = hematopoietic stem cell, Progenitor = progenitor cell, L-blast = lymphoblast, lymphocyte, Mo-blast = monoblast, monocyte, myeloblast, Pro-M = promyelocyte, myelocyte, Meta-M = metamyelocyte, neutrophil, eosinophil, basophil, Pro-E = proerythroblast, Baso-E = basophilic erythroblast, poly-E = polychromatic erythroblast, Ortho-E = Orthochromatic erythroblast, erythrocyte, promegakaryocyte, megakaryocyte, platelet.

An alternative source of beta cells, such insulin-producing cells derived from adult stem cells or progenitor cells would contribute to overcoming the current shortage of donor organs for transplantation.

Surface markers-Cell surface markers of mast cells were referred in detail by Heneberg, claiming that mast cells may be inadverently included in the stem or progenitor cell isolates since part of them is positive for the CD34 antigen.

Certain combinations of mutations in the given progenitor cell ultimately result in that cell ( also called a cancer stem cell ) displaying a number of abnormal, malignant cellular properties that, when taken together, are considered characteristic of cancer, including:

A progenitor carcinoma stem cell can be formed from any of a number of oncogenic combinations of mutations in a totipotent cell, a multipotent cell, or a mature differentiated cell.

* Recent evidence notes that exposure to hyperbaric oxygen ( HBOT ) mobilizes stem / progenitor cells from the bone marrow by a nitric oxide (· NO )-dependent mechanism.

* Granulocyte-macrophage progenitor, a type of Hematopoietic stem cell

* Hattori N, Nomoto H, Fukumitsu H, Mishima S, Furukawa S. jelly and its unique fatty acid, 10-hydroxy-trans-2-decenoic acid, promote neurogenesis by neural stem / progenitor cells in vitro.
