The new study from Kim Jensen completes the stem cell puzzle.

All organs in our body count on stem cells in order to maintain their feature. The skin is our biggest organ and forms a defense against the setting. New analysis cause by BRIC, University of Copenhagen and Cambridge University, obstacle present stem cell designs and discusses how the skin is kept throughout life. The outcomes have simply been published in the recognized diary Cell Stem Cell.

“Until now, the belief was that the skin’s stem cells were organized in a strict hierarchy with a primitive stem cell type at the top of the power structure, which this cell generated all various other cell types of the skin. Nevertheless, our results reveal that there are differentiated degrees of stem cells which it is their close micro-environment that determines whether they make hair follicles, fats- or gland, points out Kim Jensen.

The function of stem cells in skin upkeep

The study is supported by a Lundbeck Structure Fellowship, by the Danish Independent Analysis Council and the MRC and the Welcome Depend on. .
. The results are published as’advanced online publication’ on August 15th on the journal Cell Stem Cell’s homepage, where the published paper can be located from very early October: Web page et al – “The Epidermis Comprises Autonomous Compartments Maintained by Distinct Stem Cell Populations.” 10.1016 / j. stem.2013.07.010

New knowledge difficulty stem cell models

The skin contains several various cell types, featuring hair cells, fatty tissue- and sweat glands. It shields us against microbial and chemical attacks and forms a waterproof barrier that protects against fluid reduction. Associate teacher Kim Jensen’ group from BRIC have via mapping of stem cell’s behavior in the skin discovered that the skin utilizes a special technique to restore itself. Their results challenge the current perception of exactly how our skin is restored.

“We have actually marked the very early skin stem cell with beaming proteins in order to map stem cell behavior in the outer layer of the skin. The discolor is acquired by the daughter cells, so that we can map their beginning and make a family plant.

An important feature of stem cells is to fix damaged cells. Right now, the results from the Jensen groups reveal that the various stem cell populaces team up around their normal functions, to repair the skin as quick as possible. This can additionally create harm, as these modifications can “wake up” genes in the stem cells and provide rise to cancer cells. The new results subsequently also add with new knowledge on the beginning of skin cancer.

New understanding of skin cancer cells and cut recovery

Nonetheless, the outcomes give far more meaning when we connect them to the new model that our study proposes, points out Kim Jensen.

skin care section for the latest information on this topic.

“Our data completes exactly what is currently understood about the skin and its upkeep. Researchers have actually until now tried to suit their outcomes into the old model for skin upkeep.

One such instance is that it clarifies the present secret of just how skin cells could separate excessive and initiate a skin cancer, without any kind of traces of hereditary modification in the stem cells thought to preserve the outer layer of the skin. The analysis from the Jensen team may suggest that the reason that no modifications could be located is, that these cells do not join the over-proliferation at all.

“Our study will certainly now take two instructions. We will establish algebraic designs for organ upkeep in order to “determine” exactly what stem cells are finishing the skin. Also, we will expand our examinations in cancer initiation, wishing for results that can add to cancer cells diagnostics and enhanced procedure, claims Kim Jensen.
