Abstract: An automatic righting system includes a discrimination calibration module, a righting module, and a controller. The discrimination calibration module includes a distance sensing unit. The distance sensing unit is located at the front end of the glasses and configured to acquire the distance between the distance sensing unit and a first feature position. The righting module includes a push-up air cushion. The push-up air cushion is mounted at the front end of the glasses. The push-up air cushion is configured to be inflated to push the glasses to move upward. The controller is electrically connected to the distance sensing unit and the push-up air cushion. The controller is configured to control the push-up air cushion to start or stop to right the glasses according to a distance signal of the distance sensing unit.

Abstract: The described invention provides an automated, closed system and method for separating/isolating a target cell type from a heterogeneous cell population.

Abstract: The invention provides a composition comprising enriched extracellular vesicles, wherein the extracellular vesicles express VSEL markers. The extracellular vesicles are used to treat or regenerate damages or injured tissue in a subject.

Abstract: The described invention provides a composition comprising mesenchymal progenitor cells (MPC) and processes for isolating or enriching the mesenchymal progenitor cells (MPCs) having a cell surface antigenic profile of CD34(?)/CD133(?)/CD45(?)/CD73(+)/CD90(+)/CD105(+)/CD44(?). The described invention also provides methods for differentiating the mesenchymal progenitor cells (MPCs) into various cell types.
