Stem Cell Therapeutics Announces Issuance of Additional US Patent for Use of Prolactin

SCT is granted intellectual property protection in the United States covering use of prolactin for producing oligodendrocytes and treating demyelinating disease

CALGARY, ALBERTA--(Marketwire - May 19, 2009) - Stem Cell Therapeutics Corp. ("SCT") (TSX VENTURE:SSS) has been issued United States Patent No. 7,534,765, entitled "Pregnancy Induced Oligodendrocyte Precursor Cell Proliferation Regulated by Prolactin". This patent, issued today, covers methods of using of prolactin for enhancing the formation of oligodendendrocytes in vivo, such as to treat diseases associated with loss of myelin-producing oligodendrocytes (white matter diseases).

Dr. Alan Moore, President and CEO, commented as follows:

"This patent bolsters our intellectual property position around the use of prolactin for treating demyelinating neurodegenerative diseases such as multiple sclerosis ("MS") in which the myelin sheath surrounding the axon of neurons is damaged. The finding that prolactin enhances oligodendrocyte production and remyelination is what stimulated the development of our NTx®-488 program for MS, with preclinical studies being completed in preparation for Phase II clinical trials.

Importantly, as covered by other SCT patents, prolactin also stimulates neural stem cell proliferation and neurogenesis. Prolactin is therefore expected to repair both the myelin damage and the neuronal damage in MS, which is necessary for full functional recovery, and makes prolactin a unique MS drug candidate."
