A mesenchymal stem cell harvesting system and method for increasing the efficiency of collecting and processing physiological fluids containing mesenchymal stem cells from a cavity within a patient’s skeletal system. Microenvironments risk in MSC production and concentration within a cavity, for example the patient’s ilium, are penetrated with a pointed instrument used to create an aperture in the hard cortical bone forming the cavity followed by the insertion of an aspiration device which extracts one or more samples of cancellous bone, bone marrow, bone marrow blood and other aspirated material. The aspirate is rinsed and may be filtered to remove unwanted material and to increase the concentration and purity of the mesenchymal stem cells in the aspirant far beyond levels formerly obtainable for use in autologous treatment of the patient.

Compositions for treating an ocular disorder are provided. The composition includes an effective amount of a human trabecular meshwork stem cell (TMSC) secretome, wherein the effective amount is present in an amount to reduce impairment of retinal ganglion cells (RGC). Methods for treating ocular disorders using the disclosed compositions are also provided. The compositions reduce and prevent cell apoptosis, axon loss, vision loss, increased intraocular pressure, and dysregulated aqueous humor outflow of a subject when used in accordance with the methods disclosed herein.

Provided are stem cell biomimetic microparticles comprised of at least one stem cell-derived paracrine polypeptide or growth factor embedded in a polymer core particle that further comprises an outer layer of at least one fragment of a cell membrane of a stem cell disposed on the core particle. The polymer core may be constituted of any biocompatible and biodegradable polymer or copolymer, or a combination thereof that allows the embedding of the paracrine factors and their prolonged release from the core. The core and hence the microparticles can be biodegradable, allowing eventual elimination from the recipient animal or human subject. The core particles are sized to allow both transport through blood vessels and extravasation from the blood vessels into the surrounding tissues. The core particle may further include at least one polypeptide or peptide growth factor to induce the generation and proliferation of a population of stem cells.

Disclosed herein is a novel chimeric antigen receptor and use thereof. The novel chimeric antigen receptor consists of a signal peptide, an antigen binding domain, a transmembrane region, and an intracellular signal domain, and comprises a 4-1BB signal peptide and/or a 4-1BB molecular transmembrane region. Nucleic acid sequences of various chimeric antigen receptors are separated and purified and provided is a chimeric antigen receptor and a CAR-T cell which are specific for a CD19 malignant tumor antigen. In the malignant tumor killing test of hematological cell lines, the ability of immune cells to target and recognize tumor cells is significantly enhanced, and the killing activity against tumor cells is also enhanced.

Materials and methods for treating a patient with a hemoglobinopathy, both ex vivo and in vivo, and materials and methods for creating permanent changes to the genome that can result in at least one deletion, insertion, modulation, or inactivation of a transcriptional control sequence of a BCL11A gene in a cell by genome editing.

The disclosure relates to the establishment of a cell line having immune tolerance property using an optimal temperature profiling technique under a human body-like environment, and use thereof. The stem cell line exhibits immune tolerance property as they consecutively secret and express HLA-G proteins, and the culture medium of the stem cells contains a large amount of proteins capable of recovering various physiological functions and extracellular vesicles, and thus, the novel cell line or a culture medium thereof can be effectively used in various industries such as medicines and cosmetics.
