The inner root sheath cells are highly proliferative and contain excessive amount of trichohyalin
Finding follicular bulbs, papillary mesenchymal bodies, trichohyalin
granules, hair shafts, shadow cells, and focal CD34 staining in adjacent tumor stromal cells all favor benign entities.
At Australia's Queensland Institute of Medical Research, researchers identified the trichohyalin
gene as mainly responsible for creating curls.
Professor Nick Martin and Dr Sarah Medland from the Queensland Institute of Medical Research (QIMR) have discovered trichohyalin
gene that plays a vital role in development of the hair follicle.
