Polypeptides that induce cell proliferation or induce fetal hemoglobin

Patent Number: 7,241,862

This patent covers several amino acid and nucleotide sequences which are useful for modificatin of cellular differentiation and expansion. The claims refer to several sequence IDs, whereas the specification describes what appears to be numerous disjointed compositions of matter, uses, and formulations.

For example, the patent specification talks about cadherins, then IL-17, then semaphorins, and to make it even more interesting it includes phrases like "Efforts are being undertaken by both industry and academia to identify new, native secreted proteins. Many of these efforts are focused on the screening of mammalian recombinant DNA libraries to identify the coding sequences for novel secreted proteins. We herein describe the identification and characterization of novel secreted polypeptides, designated herein as PRO4357 polypeptides." Without saying what PRO4357 polypeptides are

Maybe we misread this patent, if a Genentech representative would comment on this we at StemCellPatents.com would be appreciative.
