Human Platelet Lysate as a Replacement for Fetal Bovine Serum in Limbal Stem Cell Therapy.

Purpose: To evaluate the use of human platelet lysate (HPL) as an alternative supplement for limbal explant culture.

Methods: Culture media were prepared using either 10% pooled HPL (PHPL), single donor HPL, or fetal bovine serum (FBS). Limbal tissues, obtained from the Minnesota Lions Eye Bank, were cultured in each medium on plastic plates or on denuded amniotic membrane (AM).

Exposure to DDT metabolite p,p'-DDE increases autoimmune type 1 diabetes incidence in NOD mouse model.

The incidence of autoimmune Type 1 diabetes (T1D) has been steadily rising in developed countries. Although the exact cause of T1D remains elusive, it is known that both genetics and environmental factors play a role in its immunopathogenesis. Whereas a positive association between p,p'-DDE, a DDT metabolite, and Type 2 diabetes (T2D) has been well established, its role in T1D development in an experimental animal model has never been elucidated.
