Therapeutic angiogenesis of mouse hind limb ischemia by novel peptide activating GRP78 receptor on endothelial cells
Britta Hardy, Alexander Battler, Chana Weiss, Orly Kudasi, Annat Raiter
Biochem Pharmacol (2007), doi:10.1016/j.bcp.2007.10.008
Therapeutic angiogenesis emerged as a non-invasive mean of promoting neovascularization in ischemic tissues. We have searched for new molecules that induce angiogenesis by screening a phage display [...]

Induction of Pluripotent Stem Cells from Adult Human Fibroblasts by Defined Factors
Kazutoshi Takahashi, Koji Tanabe, Mari Ohnuki, Megumi Narita, Tomoko Ichisaka, Kiichiro Tomoda, and Shinya Yamanaka
Successful reprogramming of differentiated human somatic cells into a pluripotent state would allow creation of patient- and disease-specific stem cells. We previously reported generation of induced pluripotent stem (iPS) cells, [...]
