Systems and methods for real-time tracking of photoacoustic sensing are provided. In one aspect, a method for performing in vivo analysis of a subject is provided. The method includes directing an electromagnetic excitation toward a subject to be analyzed, and acquiring, with an ultrasound probe, data about resultant waves caused by the electromagnetic excitation. The method also includes processing the acquired data to extract information related to properties of tissues in the subject, and comparing the information related to the properties of tissues in the subject using a set of criteria. The method also includes generating a report about a condition of the subject based on the comparison of the information related to properties of the tissues in the subject.

Provided are a method for preparing a highly active human mesenchymal stem cell, which includes forming a spherical cell aggregate by cultivating human mesenchymal stem cells against gravity; a highly active stem cell prepared thereby; a cell therapeutic agent including the stem cell aggregate; and a method for forming a spherical cell aggregate by cultivating human mesenchymal stem cells, wherein the amount of E-cadherin in the mesenchymal stem cell is increased during the cultivation.
摘要:
The present invention relates to a method for separating highly active stem cells from human stem cells, the highly active stem cells separated by the method, a cell therapeutic agent containing the stem cells, and a medium for separating the highly active stem cells from stem cells containing a specific cytokine. According to the present invention, the method is useful for separating the highly efficient stem cells from mesenchymal stem cells of various origins. Further, the method is very useful in developing a cell therapeutic agent of high efficiency because the method can be applicable to stem cells of various origins which are cultured under different conditions. Senescent stem cells increased by several passage times in vitro can be effectively sorted out, so the method can be used for reactivating the stem cells.

摘要:
The present invention relates to a technique of using monocytic blood cells to effectively culture and proliferate blood adult stem cells and progenitor cells that only exist in small quantities to effectively obtain large quantities of stem cells. According to the present invention, the limitation of being able to derive only small quantities of stem cells from blood can be overcome, and the pluripotency of stem cells can easily be obtained.
