Albinism in humans Albinism in humans Albinism is a congenital disorder characterized in humans by the complete or partial absence of pigment in the skin, hair and eyes. Albinism is associated with a number of vision defects, such as photophobia, nystagmus, and amblyopia. Lack of skin pigmentation makes for more susceptibility to sunburn and skin cancers. In rare cases such as Chédiak–Higashi syndrome, albinism may be associated with deficiencies in the transportation of melanin granules. This also affects essential granules present in immune cells leading to increased susceptibility to infection. Albinism results from inheritance of recessive gene alleles and is known to affect
Regeneration in humans spinal nerves. Researchers, from University of Edinburgh, have succeeded in regenerating a living organ. Regenerated organ is closely resembled with juvenile thymus in terms of architecture and gene expression profile. The thymus gland is one of the first organs to degenerate in normal healthy individuals. Between the years 2005 and 2008 four women with vaginal hypoplasia due to Müllerian agenesis were given regenerated vaginas. Up to eight years after the transplants all organs have normal function and structure. Regeneration in humans Regeneration in humans is the regrowth of lost tissues or organs in response to injury. This is in contrast
