  • Publication number: 20260083815
    Abstract: The present invention relates to a composition for inhibiting the toxicity with respect to nanoparticles and particulate matters generated from the environment. Since it has been confirmed that a decrease in intracellular ATP, a decrease in cell viability, inflammation-induced morphological changes in cells and cell activation, which are induced by nanoparticles or environmentally-derived particulate matters, are inhibited by means of the composition of the present invention, the composition may be utilized as a reducing substance for the toxicity of nanoparticles and particulate matters.

  • Patent number: 9999589
    Abstract: Provided are a culture medium of an adipose-derived stem cell, a method for preparing the same, and a composition for promoting hair growth, in which the composition includes the culture medium. The adipose-derived stem cell (ADSC-T) according to the present invention exhibits long lifespan, improved cell proliferation rate, and extended proliferation period, as compared with a primary adipose-derived stem cell (ADSC), and thus, the adipose-derived stem cell (ADSC-T) can be usefully used for the study about the adipose-derived stem cell and the mass production of the culture medium of the adipose-derived stem cell. In addition, according to the present invention, the culture medium of the adipose-derived stem cell (ADSC-T) that expresses a T antigen of SV40 exhibits excellent hair growth effectiveness and can be usefully used as a raw material for the hair loss prevention and hair growing agents.

  • Patent number: 9689019
    Abstract: Disclosed is a biomarker composition for diagnosing the toxicity of nanoparticles, which shows a change in expression by exposure to the nanoparticles, the biomarker composition comprising at least one gene selected from the group consisting of aldehyde dehydrogenase, glutamic-pyruvate transaminase, glutamate dehydrogenase, glutamicoxaloacetic transaminase, glutamic acid decarboxylase and glutamate-ammonia ligase, and to a method for evaluating the toxicity of nanoparticles using the same. The biomarker is a gene marker having a high correlation with the toxicity of nanoparticles, and the use of the biomarker can determine whether nanoparticles have toxicity, with high detection sensitivity. Also, the method is useful in monitoring or evaluating the toxicity of nanoparticles by analyzing factors having a high correlation with toxicity of nanoparticles.
