WebIntrapulmonary cystic teratoma is a rare entity and is usually a benign tumour affecting a young adult population, with no gender preference.1 Malignant transformation has been reported in 1%–2% of cases of gonadal germ cell tumours.2. Extragonadal germ cell tumours are rare with only 3% of germ cell tumours being located outside the gonads. WebSurgery got rid of my original tumor. Then I had the traditional BEP X 3 chemo which "killed" the big secondary tumor in my abdomen. Of course, I had to deal with many of the common chemo side effects such as hair loss, acid reflux, nausea, weight loss, tinnitus, neuropathy, "chemo brain", reduced cardiovascular ability, etc. dr amanda wiebe london ontario

Web2 Aug 2024 · Synopsis. Anti-apoptotic Bcl-2 protein function is required to maintain a hair follicle subpopulation of stem cells in murine skin. Blocking cell death by Bcl-2 overexpression affects the hair follicle stem cell niche and hair follicle regeneration. Systemic blocking of Bcl-2 specifically depletes supra-basal hair follicle stem cells. WebThey are located at the upper bulge, bulge, and secondary hair germ regions, though they can be replenished by neighboring cells when injured. To initiate hair regeneration, hair germ cells first proliferate and generate the differentiating lineages in response to DP signaling, followed by bulge stem cell activation. WebHair follicle morphogenesis and regeneration depend on intensive but well-orchestrated interactions between epithelial (bulge stem cells, their descendent secondary hair germ cells, and hair matrix cells) and mesenchymal (DP and dermal sheath) components. 10–13 Thus, both DP stem cells and epithelial stem cells are important, and hair growth is … dr amanda whittaker toledo
