Provided herein are novel methods and composition utilizing adipose tissue-derived stromal stem cells for treating fistulae.

A fetal stem cell-derived extracellular vesicle has immune tolerance properties. The extracellular vesicle containing a fetal stem cell-derived primal immunoglobulin contains various natural antibodies and complement proteins which can immediately respond to foreign infectious agents such as viruses, bacteria, pathogens, etc., and thus can effectively treat and prevent infectious diseases through an enhanced innate immune system. Methods are disclosed for preparing the fetal stem cell-derived extracellular vesicle.

Provided herein are enzymatically decellularized cells, and methods of producing said cells, that can be used in a scaffold. The scaffolds featured herein are biocompatible and can comprise decellularized cells that have been modified to express a bioactive agent or molecule.

The present invention provides a method for producing astrocytes from neural progenitor cells, the method comprising: (1) culturing neural progenitor cells in a culture medium comprising a neurotrophic factor; (2) dissociating the cells obtained in the step (1); and (3) subjecting the cells obtained in the step (2) to adherent culture in a culture medium comprising a neurotrophic factor using an uncoated culture vessel.

The invention pertains to the technical field of a method for isolating and expanding tendon cells in vitro. The invention also relates to cellular compositions comprising such tendon cells and use thereof to repair tendon tissue. In particular, the present invention relates to a cellular composition comprising isolated tendon cells which cells express tenomodulin (TNMD) and scleraxis (Scx).

The present invention provides methods for culturing primary cells and tissues from a subject in the presence of the subject's own serum, ascites or pleural effusion fluid. Methods of treating cancer, and screening for the effectiveness or toxicity of drugs are also provided herein.

Disclosed herein are systems, devices and methods for processing tissue, such as autologous tissue. Implementations of a Stromal Vascular Fraction (SVF) system are described that can isolate and wash harvested cells contained within various tissues, such as isolate and wash stem cells from fat tissue. The SVF system can minimize the handling and transferring of tissue and fluids, including minimizing the number of human interventions and manipulations required throughout processing. The SVF system can ensure sterility of processed tissue and harvested cells, as well as significantly reduce cost and time associated with the processing.

The present invention provides improved methods for producing RPE cells from human embryonic stem cells or from other human pluripotent stem cells. The invention also relates to human retinal pigmented epithelial cells derived from human embryonic stem cells or other human multipotent or pluripotent stem cells. hRPE cells derived from embryonic stem cells am molecularly distinct from adult and fetal-derived RPE cells, and are also distinct from embryonic stem cells. The hRPE cells described hemin are useful for treating retinal degenerative diseases.

The present application provides progenitor cells and a preparing method thereof. The preparing method comprises obtaining a tissue sample containing myometrium from uterus, treating the tissue sample with collagenase, and culturing the treated tissue sample to obtain the progenitor cells, wherein the progenitor cell is multipotent and immunomodulatory. The present application also provides a method for treating a degenerative disease, an ischemic disease or a disease caused by abnormal immune response comprising administering the progenitor cells to a patient subjecting the disease.

The invention relates to the discovery that the proliferation and survival of pancreatic progenitor cells can be enhanced by contacting the cells with, (1) a caspase inhibitor sufficient to reduce apoptosis in the pancreatic endocrine cells; and, (2) a growth factor in an amount sufficient to increase the level of activated Akt in the pancreatic endocrine cells.
