Comparison of the acute ultraviolet photoresponse in congenic albino hairless C57BL/6J mice relative to outbred SKH1 hairless mice.

ABSTRACT: Hairless albino Crl:SKH1-Hr(hr) mice are commonly utilized for studies in which hair or pigmentation would introduce an impediment to observational studies. Being an outbred strain, the SKH1 model suffers from key limitations that are not seen with congenic mouse strains. Inbred and congenic C57BL/6J mice are commonly utilized for modified genetic mouse models. We compare the acute UV-induced photoresponse between outbred SKH1 mice and an immune competent, hairless, albino C57BL/6J congenic mouse line [B6.Cg-Tyr(c-2J) Hr(hr) /J]. Histologically, B6.Cg-Tyr(c-2J) Hr(hr) /J skin is indistinguishable from that of SKH1 mice. The skin of both SKH1 and B6.Cg-Tyr(c-2J) Hr(hr) /J mice exhibited a reduction in hypodermal adipose tissue, the presence of utricles and dermal cystic structures, the pres
