Abstract: The present invention relates to a novel method for preparing an organoid using the self-assembly of spheroid. Particularly, the organoid prepared by the preparation method of the present invention has a cup-shaped morphology with a concave center, and thus, the following advantages may be obtained: nutrients and oxygen can be smoothly supplied to the center, and limitations in the size of organoid can be overcome.

Abstract: A method of controlling a magnetic resonance imaging (MRI) apparatus including performing, by the MRI apparatus, blipped-controlled aliasing parallel imaging (blipped-CAIPI) obtaining k-space data on a subject determining a phase error of a chemical shift component, wherein the phase error of the chemical shift component is proportional to a geometric error based on a resonant frequency difference between a main component and the chemical shift component in the subject comparing the k-space data with data in which the phase error of the chemical shift component is reflected, wherein the data in which the phase error of the chemical shift component is reflected is associated with data on the main component and data on the chemical shift component and determining final data for image restoration based on a result of the comparison.

Abstract: The present invention relates to a structure for tissue regeneration and to a production method therefor. The structure for tissue regeneration according to the present invention allows autologous tissue to be used, makes stable transplantation possible and can be produced without additional materials such as biopolymers. Also, it can be produced to a diameter of any desired size from a number of microns to a number of centimeters and can easily be produced in volume, and it contains large amounts of the extracellular matrix GAG, collagen and the like and can be used in tissue regeneration or filling in various fields including dermatology, plastic surgery, dentistry, surgery, orthopaedic surgery, urology, otolaryngology or in obstetrics and gynaecology.

Abstract: Disclosed herein is a method for isolating and culturing the endothelial stem/progenitor cells and mesenchymal stem cells derived from the umbilical cord of mammals, including human beings. More specifically, disclosed are a method for isolating and culturing endothelial stem/progenitor cells and mesenchymal stem cells at high purity from the umbilical cord of mammals, including human beings, and preferably from the human umbilical cord, as well as endothelial stem/progenitor cells and mesenchymal stem cells, isolated and cultured according to said method, and a method for freezing and thawing the isolated and cultured cells. According to the disclosed method, endothelial stem/progenitor cells and mesenchymal stem cells can be easily isolated and purified with high purity from umbilical cord, and can be cultured with high viability for a long period of time.
