Sentences with phrase «of hair follicle stem cells»

Conditional telomerase induction causes proliferation of hair follicle stem cells.

The bulge is where the majority of the hair follicle stem cells reside, and these can give rise to multipotent progenitor cells.

The group observed that, at the cellular level, one of the side effects of the diet was an expansion of hair follicle stem cells, leading to increasing hair follicle growth and retention rates.

Prof. Jean - Christophe Marine (VIB - KU Leuven): «Unexpectedly, this ability to divide and contribute to melanoma development contrasted with the activities of other cell populations, such as melanocyte stem cells found in hair follicles, for instance.

«Dermal papilla cells give rise to hair follicles, and the notion of cloning hair follicles using inductive dermal papilla cells has been around for 40 years or so,» said co-study leader Colin Jahoda, PhD, professor of stem cell sciences at Durham University, England, and co-director of North East England Stem Cell Institute, who is one of the early founders of the fistem cell sciences at Durham University, England, and co-director of North East England Stem Cell Institute, who is one of the early founders of the ficell sciences at Durham University, England, and co-director of North East England Stem Cell Institute, who is one of the early founders of the fiStem Cell Institute, who is one of the early founders of the fiCell Institute, who is one of the early founders of the field.

«By analyzing mice with the WNT10A mutation, as well as tissues from human patients with WNT10A mutations, we found that WNT10A regulates the proliferation, but not the maintenance, of stem cells in hair follicles,» said Sarah Millar, PhD, vice chair for Basic Research in the Department of Dermatology.

First, imaging experiments revealed that Tregs have a close relationship with the stem cells that reside within hair follicles and allow them to regenerate: the number of active Tregs clustering around follicle stem cells typically swells by three-fold as follicles enter the growth phase of their regular cycle of rest and regeneration.

Within every hair follicle is a population of melanocyte stem cells.

What they did not know in detail is what happens after those stem cells move down to the base, or bulb, of hair follicles and which cells in the hair follicles produce SCF — or that cells involved in hair shaft creation make the KROX20 protein, he said.

Scientists already knew that stem cells contained in a bulge area of hair follicles are involved in making hair and that SCF is important for pigmented cells, said Dr. Le, a member of the Hamon Center for Regenerative Science and Medicine.

Stem cells in hair follicles prove the viability of adult stem cells to not only clone, but also possibly create embryonic stem ceStem cells in hair follicles prove the viability of adult stem cells to not only clone, but also possibly create embryonic stem cestem cells to not only clone, but also possibly create embryonic stem cestem cells.

Waves of Wnt signalling spreading from hair to hair activate follicle growth, followed by waves of BMP signalling that shut down the stem cells in these follicles, halting growth.

«This is the first time anyone has made scalable amounts of epithelial stem cells that are capable of generating the epithelial component of hair follicles,» Xu says.

The epithelial stem cells, when implanted into immunocompromised mice, regenerated the different cell types of human skin and hair follicles, and even produced structurally recognizable hair shaft, raising the possibility that they may eventually enable hair regeneration in people.

But it hasn't been possible to generate sufficient number of hair - follicle - generating stem cells — until now.

They then converted the iPS cells into epithelial stem cells, normally found at the bulge of hair follicles.

First, a hair follicle contains epithelial cells — a cell type that lines the body's vessels and cavities — as well as a specific kind of adult stem cell called dermal papillae.

«Engineering blood vessels for bypass surgery, promoting the formation of new blood vessels or regenerating new skin tissue using stem cells obtained from the most accessible source — hair follicles — is a real possibility,» said Stelios T. Andreadis, Ph.D., co-author of the paper in Cardiovascular Research and associate professor in the Department of Chemical and Biological Engineering in the UB School of Engineering and Applied Sciences.

They conducted a study in mice and found that the stem cell that produces all the different cells of the skin actually lives in hair follicles.

Melanocytes have the capacity to respond to a diverse number of extracellular signals, including UVR, endocrine signaling cascades that occur during pregnancy, micro-environments of the stem cell hair bulge vs. differentiated hair follicle niches, and hypoxic conditions found in metastatic melanoma tumors.

Recent work reveals that keratinocyte holoclones contain self - renewing stem cells and that the ability to form a holoclone is an intrinsic property of the adult stem cells of the hair follicle (4).

The delicate interplay of two chemical signals coaxes stem cells into becoming hair follicles, according to new research by scientists at the Howard Hughes Medical Institute at The Rockefeller...

Your hair — or lack of hair — is the result of a lifelong tug - of - war between activators that wake up, and inhibitors that calm, stem cells in every hair follicle on your body, according to Cheng - Ming Chuong, M.D., Ph.D., of the University of Southern California (USC).
