June 2003 in “Journal of Investigative Dermatology Symposium Proceedings” The document reviewed various in vitro and in vivo models used to study hair follicles, focusing on their role in understanding hair growth and disorders like androgenetic alopecia and alopecia areata. It discussed the use of genetically modified animals and cell cultures, such as dermal papilla cells, to explore the biological and biochemical mechanisms of hair follicles. These models provided insights into the effects of androgens and growth factors on hair growth, highlighting the importance of synthesizing information from different models due to the unique characteristics of human hair growth. The research aimed to facilitate a better understanding of hair follicle function and aid in developing novel treatments for hair disorders.

August 2015 in “Stem Cells Translational Medicine” Human skin can provide stem cells for tissue repair and regeneration, but there are challenges in obtaining and growing these cells safely.
30 citations,
June 1993 in “The Journal of Cell Biology” The study examined the impact of a mutant Adenovirus E1a oncoprotein, NTdl646, on skin cells in transgenic mice, revealing that its expression led to abnormal hair follicle maturation, characterized by short, crooked hair shafts and a dystrophic or absent inner root sheath. Despite these hair follicle abnormalities, the surrounding skin remained normal, and there was no increase in skin tumors. The keratinocytes in these mice showed partial resistance to growth inhibitors, suggesting that the oncoprotein disrupted normal hair follicle development by interfering with growth regulatory proteins, without causing cancerous growth.
