dermal papilla fibroblasts

These capillaries regulate body temperature and feed epidermal … Similarly, we demonstrate that mouse DFs differentiate into mouse DPC-like cells within the hydrogel microcapsules, indicating this approach is not limited to human cell type. If scientists could find a way to stimulate the dermal fibroblast lineages from the papillary dermis in early wound healing, perhaps human skin wounds could heal without scarring and with skin appendages. We have previously shown that papillary fibroblasts are the primary source of de-novo dermal papilla during skin development, which are required for hair formation (Driskell et al., 2013). ... fibroblasts… 2013 Dec 12;504(7479):277-281. doi: 10.1038/nature12783.

Understanding the impact of fibroblast heterogeneity on skin fibrosis. Fibroblast heterogeneity: more than skin deep. Clipboard, Search History, and several other advanced features are temporarily unavailable. The dermal papilla (DP) is a cluster of specialized fibroblasts at the base of each follicle, and has a critical inductive role in hair follicle development (Yang and Cotsarelis, 2010; Millar, 2002). But exactly how dermal papilla forms has remained elusive until now. The induction of dermal fibroblasts into DPC-like cells through biomimetic microencapsulation, devoid of chemical or gene reprogramming, would provide an alternative, abundant, and safe source of DPCs, which would help circumvent the bottleneck in DPC-based HF regeneration. During aging, stromal functions are thought to be impaired, but little is known whether this stems from changes of fibroblasts. In vitro, the presence of DPCs induced a more … The development of novel sources of human dermal papilla cells (hDPCs) is of great significance to hDPC-based hair follicle regeneration strategies. 1!

With their ability to liberate growth factors, lay down fibroelastic matrices, and proliferate at sites of inflammation, fibroblasts play critical roles in wound healing, tissue repair, and remodeling. Dermal fibroblasts exhibit considerable heterogeneity during homeostasis and in response to injury. 2020 Sep 8;9(9):2047. doi: 10.3390/cells9092047. In addition, there are condensations of fibroblasts, called the dermal papilla (DP), at the base of the HFs, fibroblasts that ensheath the HF [dermal sheath (DS) cells] and smooth muscle cells in the arrector pili … Understanding the contribution of the dermis in skin aging is a key question, since this tissue is particularly important for skin integrity, and because its properties can affect the epidermis.

Soon after, a local condensation (dermal condensate) of fibroblasts … For example, papillary fibroblasts (PFi) are located in the upper dermis, adjacent to the epithelium, whereas reticular fibroblasts (RFi) are found in the lower dermis. Microarray data showed that DP cells and dermal fibroblasts originate from common fibroblast progenitors in the developing embryonic mouse skin and have highly correlated gene expression profiles (96%). The development of novel sources of human dermal papilla cells (hDPCs) is of great significance to hDPC-based hair follicle regeneration strategies. Current approaches fail at obtaining adequate functional human dermal papilla cells (DPCs) to regenerate hair follicles (HFs). The dermal papillae (DP) (singular papilla, diminutive of Latin papula, 'pimple') are small, nipple-like extensions (or interdigitations) of the dermis into the epidermis.
