Morphology study of freeze-drying mononuclear cells of human cord blood
The residual moisture content was 6.5±0.87%. The recovery of the cells was tested by a haemacytometer, and the numerical cell count recovery of rehydrated MNC increased by 8%. Morphology of the fresh and rehydrated MNC was analyzed respectively using standard light microscopy, scanning electron microscope and transmission electron microscope. The results showed that karyons changed and cytoplasm decreased after rehydration, but it is still unknown that whether these changes will influence the proliferative ability of the stem cells.

CryoLetters is a bimonthly international journal for low temperature sciences, including cryobiology, cryopreservation or vitrification of cells and tissues, chemical and physical aspects of freezing and drying, and studies involving ecology of cold environments, and cold adaptation
The journal publishes original research reports, authoritative reviews, technical developments and commissioned book reviews of studies of the effects produced by low temperatures on a wide variety of scientific and technical processes, or those involving low temperature techniques in the investigation of physical, chemical, biological and ecological problems.
