Observational Study Clinical Trial
Official title:
Exploring the Effectiveness and Factors Affecting the Collection of Single Nucleated Cells From Different Volunteers
1. 80 cases of healthy donors were subjected to peripheral blood single nucleated cells (PBMC) collection and analyzed the effects of age, body mass index (BMI), blood routine indexes before collection, collection of circulating blood volume, volume of processed blood and the number of circulations, etc., on the PBMC obtained from both men and women, and explored the effects of PBMC collection in different volunteers and the factors affecting the collection. and the influencing factors. 2. The data obtained will provide a reference for the MNC threshold for the subsequent clinical trials of immunocell therapy in hospitals. 3. From the screening of volunteers, PBMC collection and transportation conditions and other specific details of the operation, risk assessment and the establishment of a safe operation standard process, for the hospital to carry out subsequent clinical trials of immune cell therapy to provide an effective reference.
