April 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that using trypsin digestion to extract keratinocytes from the hair follicle bulge results in a higher yield and faster growth of stem keratinocytes compared to the explant method.
December 2025 in “Rapid Communications in Mass Spectrometry” This study found that pepsin digestion was more effective than trypsin at identifying keratin-associated proteins in human hair shafts and confirmed that trypsin introduced a bias in the analysis of protein composition that pepsin can correct.
January 2006 in “Zhongguo bijiao yixue zazhi” This study demonstrated a simple and efficient method to isolate epithelial cells from rat vibrissa follicles, reducing labor and contamination risk while maintaining positive K19 staining.
April 2023 in “Journal of Investigative Dermatology” In this study, trypsin digestion was found to be a faster and more efficient method than the explant technique for extracting bulge-derived keratinocytes from adult scalp biopsies.
January 2008 in “Zhongguo zuzhi gongcheng yanjiu yu linchuang kangfu” This study found that selecting human vaginal mucosa stem cells by adhesion to type Ⅳ collagen for 20 minutes and culturing them with feeder layer and epidermal total culture media was most effective in maintaining their characteristics.
