About StemCells, Inc.

StemCells, Inc. is currently engaged in clinical development of its platform technology, HuCNS-SC® (purified human neural stem cells) as a potential treatment for disorders of the central nervous system (CNS). Top line data from the Company's Phase I/II clinical trial in thoracic spinal cord injury (SCI) showed measurable gains involving multiple sensory modalities and segments, including the conversion of 2 of 7 patients enrolled in the study with complete injuries (AIS A) converting to incomplete injuries (AIS B), post-transplant.
