In some aspects, disclosed herein are methods and compositions for treatment or prevention of CNS disorders (e.g., stroke) using fibroblasts or derivatives thereof. Disclosed herein are fibroblasts and derivatives thereof capable of inducing neuroregeneration and/or reducing neuroinflammation in a subject. Aspects comprise methods and compositions for stimulating neural progenitor cell proliferation. In some cases, methods comprise providing fibroblasts and stem cells (e.g., hematopoietic stem cells) to an individual to treat or prevent a stroke. Embodiments are directed to exosomes or other microvesicles (e.g., apoptotic bodies) derived from fibroblasts for use in treating or preventing stroke in an individual. In some aspects, disclosed are means, methods, and compositions of matter useful for treatment of cerebral hemorrhage through administration of fibroblasts, modification of fibroblasts, and/or derivatives of fibroblasts such as exosomes, microvesicles, and/or apoptotic bodies. In one embodiment, fibroblasts, modified fibroblasts, and/or derivatives thereof are administered for induction of neuroprotective properties and/or stimulation of neuroregeneration.

A method for treating a cancer of similar or same histological type is provided. The method includes administering a xenogeneic tissue cell composition to a subject in need for a treatment of the cancer of similar or same histological type. The xenogeneic tissue cell composition does not include a tumor cell, and the xenogeneic tissue cell composition is administered to the cancer of the similar or same histological type by an intralesional route.

This disclosure relates to endothelial and smooth muscle like vascular tissue produced from urine cells. In certain embodiments, the disclosure relates to methods of producing endothelial and smooth muscle like vascular tissue by exposing urine derived cells with ETV2 in a first growth media under conditions such that the cells are modified to form a pool of cells expressing increased levels of endothelium surface markers and thereafter exposing the pool of cells to a second growth media under conditions such that the cells are modified to form tissue containing cells expressing increased levels of smooth muscle surface markers in addition to the endothelium surface markers. In certain embodiments, the disclosure relates to using cells and tissues reported herein for the treatment of vascular, cardiac, and wound healing indications.
