The embodiments of the present disclosure provide a manufacturing method of mitochondria-rich plasma. The mitochondria-rich plasma can increase the cell viability of damaged cells, decrease the cellular senescence level, repair the oxidative damage of cells, and relieve the inflammation of hair follicles so as to achieve the purpose of promoting hair regrowth.

Methods for generating in culture of cells resembling mammalian trophectoderm-lineage cells from mammalian pluripotent stem cells are provided, along with the related compositions.

The present invention relates to a cord blood plasma-derived exosome or a mimetic thereof and a pharmaceutical use thereof. More particularly, the present invention provides the use of a human cord blood plasma-derived exosome or an exosome mimetic that mimics the proteomic profile of the cord blood plasma-derived exosome for the improvement, prevention or treatment of various autoimmune diseases or wound healing.

Embodiments of the disclosure encompass systems, methods, and compositions for producing exosomes from primed mesenchymal stem cells that are expanded in the presence of IFNγ, TNFα, IL-1β, and IL-17. The systems, methods, and compositions ay occur in an automated cell expansion system that allows for controllable parameters and from which cells and exosomes may be harvested at one or more times as part of a particular regimen. In specific embodiments, the exosomes may be provided to an individual in need thereof, including in some cases when the exosomes comprise one or more therapeutic agents.

Disclosed herein is a formulation comprising an extracellular vesicle (EV), and a therapeutic active agent induced or embedded in the EV. According to preferred embodiments of the present disclosure, the EV is isolated from umbilical cord mesenchymal stem cells, and the active agent may be a growth factor, an immune-modulating agent, a small molecule, an siRNA, cDNA or a plant ingredient; for example, curcumin. Also disclosed herein are methods for producing the present formulation, and uses of the present formulation in the treatment of various diseases.

The invention relates to a device for isolating stem cells from fetal tissues, which device has an incubation chamber, at least one pump, at least one reservoir for a tissue break-down solution, at least one reservoir for a rinsing solution, optionally a control unit, optionally a means for removing contaminants, and optionally a means for expansion of the isolated stem cells. The invention further relates to a method for isolating stem cells from fetal tissue, which method comprises, among other things, the mechanical dissociation and the enzymatic digestion of the fetal tissue and optionally density gradient centrifugation for removing contaminants. The device and the method according to the invention are particularly suitable for isolating mesenchymal stem cells from fetal tissues, such as umbilical cord tissue, placenta tissue, or fetal lung tissue.

A method for enhancing an expression of insulin like growth factor 1 receptor in a mesenchymal stem cell is provided. The method includes culturing the mesenchymal stem cell expressing insulin-like growth factor 1 receptor in a medium containing platelet-derived growth factor BB (PDGF-BB) to enhance the expression of insulin like growth factor 1 receptor in the mesenchymal stem cell.

An object is to develop technology for viral inactivation. As means for resolution, viruses are inactivated by irradiating various articles with microwaves.

The present invention provides a method for reprogramming a human somatic cell to a cell exhibiting at least one characteristic of a trophoblast stem cell (TSC), the method comprising the following steps in order: a) increasing the protein expression of one or more factors in the somatic cell, wherein the factors are for reprogramming the somatic cell towards a pluripotent state; b) culturing the cell for a sufficient time and under conditions to allow the reprogramming of the cell towards a pluripotent state; c) contacting the cell with a culture medium suitable for sustaining trophoblast stem cells (TSC); and d) culturing the cell in the TSC medium for a sufficient time and under conditions to allow the cell to exhibit at least one characteristic of a TSC, thereby reprogramming the somatic cell to a cell exhibiting at least one characteristic of a TSC.

An object of the present invention is to provide a cell population comprising adherent cells having low differentiation capacity derived from a fetal appendage, methods for producing or using the same, and a pharmaceutical composition comprising the cell population, in particular wherein the proportion of CD73- and CD90-positive adherent cells derived from a fetal appendage is 90% or more; and the cell population satisfies a relative expression level of LFA-3 gene to the expression level of SDHA gene of 1.0 or more, in particular wherein the relative expression level of HAPLN1 gene to the expression level of SDHA gene is 4.0 or more and/or the relative expression level of CCND2 gene to the expression level of SDHA gene is 1.5 or less, in particular wherein the proportion of the STRO-1-negative adherent cells derived from a fetal appendage is 95% or more.
