Effects of oxytocin on the hair growth ability of dermal papilla cells

Project description:Oxytocin (OXT) is a neuropeptide hormone termed “love hormone” that is produced and released during childbirth and lactation. It is also produced in response to stimulation of the skin (e.g., during hugging and massaging) and music therapy, among others. The effects of OXT on various organs have been revealed in recent years; however, the relationship between hair follicles and OXT remains unclear. In this study, we examined the effects of OXT on dermal papilla (DP) cells, that control hair growth by secreting growth/regression signals. Gene expression analysis revealed that DP functional markers were significantly upregulated in DP cells treated with OXT. In addition, we tested the hair growth-promoting effects of OXT using in vitro hair follicle organoids. OXT promoted the growth of hair peg-like sprouting by upregulating the expression of hair growth-promoting factors including genes encoding vascular endothelial growth factor A (VEGFA). This study highlights the positive effects of OXT in hair follicles and may assist in the development of new treatments for alopecia.

Global profiling of human hair follicle scalp dermal papilla cells using Affymetrix microarrays

Project description:Dermal papilla cells isolated from the human hair follicle are capable of inducing hair growth in recipient epithelia. However, demonstrating disparity from rodent dermal papilla, human cells lose this inductive competance immediately upon growth in culture under normal growth conditions. We grew dermal papilla cells in hanging drop cultures that are morphologically akin to intact dermal papilla, and found that by enhancing the environment for aggregation, we could restore the inductive capacity of human dermal papilla cells in culture. The underlying genes that regulate the inductive potential of dermal papilla cells is not well understood, and we sought to use global profiling to identify key genes and pathways related to inductive competance within dermal papilla cells. We used Affymetrix microarrays to profile human dermal papilla cells in both hair inducing, and non-hair inducing states. Affymetrix microarrays were used to to perform profiling of human dermal papilla cells, both as intact tissues (freshly isolated from scalp), and at several stages in subsequent two dimensional culture; cell explant outgrowths (p0), cells at passage 1 (p1), passage 3 (p3) and passage 5 (p5). RNA was isolated from cultured cells 72 hours after feeding. Cells at passage 3 were also grown in hanging drops to form dermal spheroids, that were used for RNA collection 48 hours after establishment. All experiments were performed using tissue from three biological replicates (#D5, D6, D7),
