Hello manoj kumar valluru,
An interesting week in terms of new ways of stimulating hematopoietic stem cells. Patent #7,442,390 issued covering the use of specific populations of mesenchymal-like cells for augmenting hematopoietic stem cell engraftment, whereas patent # 7,442,394 also issued, teaching the use of blueberries and other natural products in the development of a composition that activates "stem cells". Yet again this week, Jamie Thomson was awarded another patent (#7,442,548), this time for an expansion of previous work, essentially showing that various supplements can be added to serum-free media to allow embryonic stem cell expansion without differentiation.
Neat paper was also published last week, first time demonstration of CTLA-4 blockade in post hematopoietic stem cell transplant relapse patients. Although it was a dose-finding study, 3 patients underwent objective disease response with a one-injection protocol. The ability to stimulate immune suppression through inhibition of an inhibitor was previously discussed in the write-up we did on removal of cancer-secreted exosomes.
