April 2002 in “Animal Science” This study found that intradermal spermidine injections stimulated cell proliferation and increased fibre length growth rate in wool follicles of Merino lambs, without significantly affecting fibre diameter.
This study found that human hair exhibits significant deformation in its intermediate filaments under strain, with recovery taking about 1000 minutes, suggesting a self-healing period post-mechanical stress. Additionally, cuticle scales deform much less than the cortex, and the Poisson ratio aligns with soft matter properties.
