RIKEN and Hitachi succeed in automated culture of retinal pigment epithelial (RPE) cell sheets derived from human iPS cells

A joint research team of Hitachi and RIKEN have successfully used a completely closed  automatic cell culture system for culturing RPE cell sheets derived from human iPS cells. using a culture device. By analysis of various markers it was demonstrated that these RPE cell sheets showed the same level of quality as those cultured by skilled […]

RIKEN researchers prepare adhesive silk by tyrosinase-catalysed oxidation

Hiromitsu SUGAKAWA and colleagues at RIKEN Bioresources Research Center have treated an aqueous silk protein solution with tyrosinase, thereby converting tyrosine residues in silk to DOPA. Amino acid analysis by ninhydrin confirmed that the treated silk contained about 1 mol% of DOPA. The adhesiveness of this DOPA-containing silk protein was greatly improved, especially under basic conditions, […]
