Description

Technical Field

[0002] Preparation of umbilical cord-derived mesenchymal stem cells requires extraction of Wharton's jelly from umbilical cord tissue. The key technical point of the method of extracting Wharton's jelly is the composition and structural characteristics of umbilical cord tissue.

[0003] The umbilical cord tissue presents the structural characteristics of "randomly curled structure of polysaccharide chains", and the umbilical cord tissue is composed of the following: Umbilical cord: The most obvious part of the umbilical cord is the umbilical cord, which usually includes two umbilical arteries and one umbilical vein. Mucous tissue: The inside of the umbilical cord is filled with a substance called mucous tissue or Wharton's jelly, which is a gel-like substance rich in polysaccharides (mainly Wharton's jelly) and collagen. Umbilical cord membrane: The umbilical cord is wrapped by the umbilical cord membrane, which is a thin membrane composed of amnion and chorion, which helps to maintain the structural integrity of the umbilical cord and provides a certain degree of protection.

[0004] Currently, the extraction of Wharton's jelly is done by tearing open the umbilical artery and umbilical vein with tweezers along the spiral pattern (random curled structure of polysaccharide chains), removing the umbilical artery and umbilical vein, fixing the untied umbilical cord tissue with tweezers in the left hand, and clamping the Wharton's jelly with tweezers in the right hand. The above-mentioned blunt extraction method is inefficient in extracting Wharton's jelly: most of the Wharton's jelly is not completely extracted, it takes a long time, the operator uses tweezers to perform long-term delicate operations, which may cause occupational injuries or discomfort (such as wrist pain, finger cramps, shoulder and neck fatigue, eye fatigue, etc.), and it is costly for technicians to cultivate this skill.
