IIT-D makes silk-based hair follicle to avoid animal testing

In a first, IIT Delhi researchers have developed a silk-based hydrogel that emulates human hair growth, and may help screen drugs for treating hair loss without animal tests. Researcher Sourabh Ghosh said physiological differences amongst animals and humans drastically limit the success of such drugs, which prompted the need for 3D in-vitro model of hair follicle using human cells.
