We measured the dynamics of an essential epigenetic modifier, HP1β, in human cells at different stages of differentiation using Fluorescence Recovery After Photobleaching (FRAP). We found that HP1β mobility is similar in human embryonic stem cells (hES) and iPS cells where it is more mobile compared to fibroblasts; HP1β is less mobile in senescent(More)
Induced pluripotent stem (iPS) cells have provided a rational means of obtaining histo-compatible tissues for 'patient-specific' regenerative therapies (Hanna et al. 2010; Yamanaka & Blau 2010). Despite the obvious potential of iPS cell-based therapies, there are certain problems that must be overcome before these therapies can become safe and routine (Ohi(More)
Whey is a dairy product containing milk serum proteins with diverse biological effects. In this study, the effect of dietary whey supplementation on wound healing was investigated. Rats were fed a standard or whey-supplemented diet for three weeks. Wound healing parameters, glutathione, and lipid peroxide levels were determined three days after the(More)
Mammals have three HP1 protein isotypes HP1β (CBX1), HP1γ (CBX3) and HP1α (CBX5) that are encoded by the corresponding genes Cbx1, Cbx3 and Cbx5. Recent work has shown that reduction of CBX3 protein in homozygotes for a hypomorphic allele (Cbx3 hypo) causes a severe postnatal mortality with around 99% of the homozygotes dying before weaning. It is not known(More)
A half-thickness wound was inflicted on a rabbit in the central part of the cornea by means of a trephine 4 mm in diameter. Subconjunctival and subcutaneous injections of ethanolamine were given to stimulate regeneration. In control animals destructive processes predominated in the early stages and epithelization was complete on the 15th–16th days. A coarse(More)
