Force-Triggered Density Gradient Sedimentation and Cocktail Enzyme Digestion Treatment for Isolation of Single Dermal Papilla Cells from Follicular Unit Extraction Harvesting Human Hair Follicles

The study introduces two innovative methods, force-triggered density gradient sedimentation (FDGS) and cocktail enzyme digestion treatment (CEDT), for isolating single dermal papilla cells (DPCs) from human hair follicles, involving 12 male participants aged 25-35. These methods address the limitations of traditional techniques by improving the purity and yield of DPCs, crucial for hair follicle research and therapeutic applications. FDGS separates DP spheres using a 10% Ficoll PM400 concentration, while CEDT efficiently isolates fresh DPCs without compromising cell viability, proliferation, or migration. The methods preserve DP-specific markers and reveal significant transcriptional differences compared to traditional cultures, enhancing their potential for tissue engineering and regenerative medicine.
