| Cancer is one of the major diseases which threatens human health, but traditional treatment methods fail to completely
eradicate cancer. Because of the complexity of the pathogenesis of cancer, it has not been known clearly. Proposing the theory of cancer
stem cells for tumor occurrence and development of recurrence provides a new research idea, also brings a new dawn for the treatment of
cancer. However, cancer stem cells are extremely rare in tumors, it is very difficult to isolate CSC. At present, commonly used methods
for the isolation of cancer stem cell are serum-free culture and flow sorting. It is urgent to establish a new effective separation method
because of both of them having certain shortcomings. Cancer stem cells and normal stem cells have many similar signaling pathways, so
we can mimic stemcells microenvironment to select lower differentiation tumor stemcells. Hydrogel is widely used in three-dimensional
cell culture due to its unique properties. Researchers use hydrogels simulate the mechanics microenvironment of stem cells to seclect and
enrich cancer stemcells. This article reviewed a few main streamisolation and identification methods of cancer stemcells combined with
the latest research at home and abroad. |
