Primary bioassay of human tumor stem cells
Patent Number: 4411990Cancer stem cells have been known to exist for decades, as seen by the present patent whose actual first priority date is july 7, 1978. Unfortunately, research into cancer stem cells is only recently gaining attention. The cancer stem cell is the populatin which some believe is responsible for maintaining the tumor mass, while the other 99% of cancer cells are differentiated and have...

Enhanced growth medium and method for culturing human mammary epithelial cells
Patent Number: 4423145This patent covers ways of growing mammary epithelial tissue in vitro. It teaches that such cells can be grown through dissociating stromal cells using enzymez and mechanical means so as to obtain a population of clumps of epithelial cells. The epithelial cells are then grown in a conditioned media that is either conditioned by human fetal intestine epithelial cells or human bladder epithelial...

Method for producing substance capable of stimulating differentiation and proliferation of human granulopoietic stem cells
Patent Number: 4342828This patent teaches how to make a hematopoietic-stimulatory substance through taking out blood, extracting monocytes and macrophages, culturing them with a glycoprotein from urine, and collecting/concentrating the resulting composition, which is useful for stimulating the proliferation and differentiation of human granulopoietic stem cells. This may be an interesting way to generate growth...
