The present invention provides a composition for treating ischemic diseases or neuroinflammatory diseases. PSA-NCAM-positive neural progenitor cells used in the present invention promote angiogenesis in injected tissue and inhibit an inflammatory response. The PSA-NCAM-positive neural progenitor cells can be simply isolated by using an anti-PSA-NCAM-antibody, and exhibit excellent angiogenic and anti-inflammatory activities compared with mesenchymal stem cells, and thus can be useful as a composition for effectively treating ischemic diseases caused by a vascular injury and nerve damage diseases caused by inflammation. In addition, a secretome of the neural progenitor cells of the present invention reduces the ischemic injury site and allows a neurological function to recover, and thus can be used as an agent for treating ischemic diseases and degenerative nervous system disorders such as nerve damage diseases caused by inflammation.

Production of “regenerative medicine products” is facilitated using a quality by design (QbD) approach. A production device produces a medical product and analyzes a starting material and a central management device determines processing conditions in the production device. By transmitting and receiving data pertaining to the starting material between the production device and central management device data, the medical product is produced while production conditions therefor are continuously optimized. Thus, it is easy to produce a medical product while reducing or eliminating effects from changes in cells and tissues over time, from oscillation during transport, and from changes in surrounding environment such as changes in temperature, and to produce the desired medical product even when there are individual differences in the starting material.

The invention relates to a human in vitro model and a method of constructing the same to mimic the alveolar region of the airways to assess the respiratory toxicology and/or physiological and/or biological response of inhaled products, chemicals and particles.

Disclosed are means of enhancing therapeutic activities of fibroblasts through manipulation of nuclear receptor activation accomplished by, intra alia, alteration in hormone levels. In some embodiments angiogenic, and/or neurogenic, and/or immunomodulatory activities of fibroblasts are increased by normalization or augmentation of sex-specific hormones. In one embodiment a candidate for fibroblast therapy is administered hormones, pro-hormones, or growth factors to augment therapeutic activities of fibroblasts. In some embodiments fibroblasts are treated in vitro prior to administration with various hormones and/or growth factors in order to augment therapeutic activities of said cells.

The current disclosure provides methods for reprogramming mammalian somatic cells by regulating the expression of endogenous cellular genes. Cellular reprogramming of somatic cells can be induced by activating the transcription of embryonic stem cell-associated genes (e.g., oct3/4) and suppressing the transcription of somatic cell-specific and/or cell death-associated genes. The endogenous transcription machinery can be modulated using synthetic transcription factors (activators and suppressors), to allow for faster, and more efficient nuclear reprogramming under conditions amenable for clinical and commercial applications. The current disclosure further provides cells obtained from such methods, along with therapeutic methods for using such cells for the treatment of diseases amendable to stem cell therapy, as well as kits for such uses.
