  • Patent number: 11833176
    Abstract: The present invention relates to a pharmaceutical composition for preventing or treating neonatal hypoxic ischemic encephalopathy (HIE), comprising thrombin-treated stem cells or exosomes derived therefrom as an active ingredient, and a method for producing the same. According to the present invention, the thrombin-treated stem cell or the exosome derived therefrom has an increased expression of growth factors, immunoregulatory factors, antioxidation factors, or regeneration factors compared to a group not treated with thrombin and also enhances a neuronal apoptosis inhibitory effect, and thus has an advantage in that the therapeutic effect thereof on neonatal hypoxic ischemic encephalopathy (HIE) is excellent.

  • Publication number: 20230256021
    Abstract: The present invention relates to: a pharmaceutical composition which is for preventing or treating diabetic skin disease, and comprises, as an active ingredient, an exosome derived from a thrombin-treated stem cell; a pharmaceutical formulation containing said composition; and a method for producing same. In the present invention, an exosome isolated from a thrombin-treated stem cell was found to have an excellent effect on the recovery of diabetic animal models from diabetic dermatopathy. In addition, since exosome-based therapeutics are cell-free formulations and thus do not include DNA, such therapeutics have a low risk of cancer and are free of cell surface antigens. Accordingly, exosome-based therapeutics do not have the issue of transplant rejection and are thus safe. Accordingly, the exosome derived from a thrombin-treated stem cell according to the present invention can be developed as a therapeutic agent for various intractable chronic skin diseases that can be caused by diabetes.

  • Publication number: 20230028447
    Abstract: The present invention relates to a screening method for a therapeutic agent for pulmonary damage induced by the administration of high-concentration oxygen, and more specifically, to a screening method for a candidate material for a therapeutic agent for bronchopulmonary dysplasia (BPD) induced by the administration of high-concentration oxygen. The present inventors have discovered that FPR1 is over-expressed in lung tissues exposed to high-concentration oxygen, and as a result of focusing on the correlation between the expression of FPR1 and the development of BPD, have confirmed that BPD can be suppressed by inhibiting the expression or activity of FPR1. In view of this fact, a prophylactic or therapeutic material for BPD may be discovered in a rapid and accurate manner by checking whether the expression or activity level of FPR1 is inhibited, and thus, the screening method of the present invention may be beneficially used to effectively select and develop therapeutic agents for BPD.

  • Publication number: 20210255169
    Abstract: The present disclosure relates to a method of selecting stem cells having the ability to produce extracellular vesicles with high efficiency, the method including the step of measuring the activity of protease-activated receptor (PAR)-mediated signaling pathways, stem cells selected by the method, and a method of screening an inducer for the production of extracellular vesicles. According to the present disclosure, upon treatment of stem cells with thrombin, the production of extracellular vesicles in the stem cells and the levels of proteins in the extracellular vesicles are significantly increased via PAR-mediated signaling pathways, and thus stem cells having the ability to produce extracellular vesicles with high efficiency can be efficiently selected by treating stem cells with thrombin and measuring an activation level of a PAR-mediated signaling pathway, and stem cells selected by this method can be effectively used in related research and clinical fields.
