research LB788 Development of a novel three-dimensional human epidermal model from plucked hair follicle-derived keratinocytes
Scientists created a new 3D skin model from cells of plucked hairs that works like real skin and is easier to get.
research Novel tissue mechanics-guided cellular flows drive the formation of feather follicles
The study investigates the formation of feather follicles in avian skin using chicken and transgenic quail skin models. It reveals that novel cellular flows initiate chemo-mechanical circuits that guide the morphological transitions necessary for feather bud formation. Initially, stiff dermal condensates protrude from a softened epithelial sheet, activating YAP and causing the epithelial sheet to fold and form a cylindrical wall that invaginates into the skin. This process is crucial for forming tightly packed dermal papillae. The study contrasts this with scale development, where a rigid epithelial sheet restricts dermal cell flows, preventing further transformation. A topological transformation model was developed to describe how feather follicles evolved from scales.
