MESENCHYMAL-LIKE STEM CELLS DERIVED FROM HUMAN EMBRYONIC STEM CELLS, METHODS AND USES THEREOF
The disclosure provided herein relates generally to mesenchymal-like stem cells hES-T-MiSC or T-MSC and the method of producing the stem cells. The method comprises culturing embryonic stem cells under conditions that the embryonic stem cells develop through an intermediate differentiation of trophoblasts, and culturing the differentiated trophoblast in hES-T-MSC or T-MSC, T-MSC derived cells and cell lineages T-MSC-DL are also described. Disclosed also herein are solutions and pharmaceutical compositions comprising the T-MSC and/or T-MSC-DL, methods of making the T-MSC and T-MSC-DL, and methods of using the T-MSC and T-MSC-DL for treatment and prevention of diseases, specifically. T-MSC and T-MSC-DL are used as immunosuppressive agents to treat multiple sclerosis and autoimmune diseases.
Composition comprising induced exosome for hair regeneration
A method for producing exosomes comprises steps of: providing ultrasound stimulation directly or indirectly to cells; culturing a mixture of the cells and a medium for a predetermined time; and isolating exosomes from the mixture, wherein providing the stimulation directly to the cells comprises applying ultrasound stimulation to the medium containing the cells, and the providing the stimulation indirectly to the cells comprises applying ultrasound stimulation to the medium not containing the cells and then mixing the medium and the cells. This method for producing exosomes makes it possible to obtain exosomes having a hair regeneration effect not only from stem cells and progenitor cells that are difficult to isolate and multiply, but also from somatic cells that may be easily obtained and maintained, in high yield within a short time by ultrasound treatment that is a simple process.
Method of repairing damaged chondrocytes via low-dose irradiation
The present invention relates to a method for inhibiting an inflammatory response in chondrocytes, and dedifferentiation or destruction of chondrocytes by irradiating damaged chondrocytes with low-dose radiation, and a method of treating a disease of cartilage by irradiating damaged chondrocytes with low-dose radiation.
METHOD FOR PREVENTING CANCERIZATION DUE TO LOW-DOSE IRRADIATION
The present invention relates to a method for preventing cancerization of normal cells due to low-dose irradiation. The method enables effective prevention of cancerization of normal cells by means of low-dose radiation which is innocuous to a subject.
3D LABEL-FREE CONTACTLESS FORMATION OF CELLULAR STRUCTURES AND CO-CULTURES THROUGH DIAMAGNETOPHORESIS
A novel macroscale, contactless, label-free method to print in situ three-dimensional (3D) particle assemblies of different morphologies and sizes is demonstrated using non-adherent (blood) and adherent (MCF-7 and HUVEC) cells. This method of manipulating particles such as cells or biological moleules does not necessarily require the use of nozzles that can contaminate the cell suspension, or to which cells can adhere. Instead, the intrinsic diamagnetic properties of particles such as cells are used to magnetically manipulate them in situ in a nontoxic paramagnetic medium, creating various shapes such as (a) rectangular bar, (b) three-pointed star, and (c) spheroids of varying sizes. A normal distribution of 3D cell structures is produced when formed through magnetic assembly. The use of this method in co-culturing of different cell lines is also demonstrated. The technique is envisioned to be transferable to other cell lines or diamagnetic biological molecules, with potential applications in tissue engineering, medical diagnostics and drug screening.
THERAPEUTIC USE OF ELECTROACUPUNCTURE-INDUCED MESENCHYMAL STEM CELLS
Stimulation using EA of LI-4, LI-11, GV-14 and GV-20 in humans, horses, and rodents results in mobilization of MSCs into systemic circulation. Methods are provided for increasing mesenchymal stem cells in the circulating blood of a mammal by contacting acupuncture points LI-4, LI-11, GV-14, and GV-20 of the mammal with a therapeutically effective amount of EA stimulation to mobilize MSCs into the circulating blood of the mammal. Methods for treating damaged tissue, specifically damaged tendons are also provided. Isolated mesenchymal stem cells made according to these methods, methods of isolated them, and stem cell banks that store them are also provided.
CELL REPROGRAMMING METHOD USING IMPOSITION OF PHYSICAL STIMULATION-MEDIATED ENVIRONMENTAL TRANSITION
The present invention relates to a cell reprogramming method using a physical stimulation-mediated environmental influx, and more specifically, by subjecting differentiated or non-differentiated cells to physical stimulation which can promote an environmental influx, such as ultrasonic waves, laser or heat shock, without the introduction of a reprogramming-inducing factor or a chemical substance to the differentiated cells, the cells can be reprogrammed with just the imposition of an external environmental influx into pluripotent cells or arbitrary differentiated cells having a different expression type from the differentiated or non-differentiated cells, and as such an inducement has a simple and effective production process, the possibility of an autogenic cell therapy can be made greater.
Magnetic extracellular matrix
Methods of making and using a magnetic ECM are disclosed. The ECM comprises positively and negatively charged nanoparticles, wherein one of said nanoparticles contains a magnetically responsive element. When the magnetic ECM is seeded with cells, the cells will be magnetized and can be levitated for 3-D cell culture.
COMPOSITIONS AND METHODS FOR ACTIVATING NK CELLS
The present invention is based, in part, on cancer vaccine compositions or pharmaceutical compositions comprising cancer cells, monocytes, and/or osteoclasts that activate NK cells, and methods for using same to prevent and/or treat diseases such as cancer.
Mesenchymal-like stem cells derived from human embryonic stem cells, methods and uses thereof
