Autonomous driving, automatic speech recognition, and the game Go: Deep Learning is generating more and more public awareness. Scientists at the Helmholtz Zentrum MA1 4nchen and their partners at ETH Zurich and the Technical University of Munich have now used it to determine the development of hematopoietic stem cells in advance.

Newly discovered breast stem cells wake up when exposed to ovarian hormones
Walter and Eliza Hall Institute researchers have used advanced cellular, bioinformatics and imaging technology to reveal a long-lived type of stem cell in the breast that is responsible for the growth of the mammary glands during pregnancy. The newly discovered stem cells, which respond to the ‘ovarian hormones’ progesterone and oestrogen, may also be linked to a high-risk form of breast cancer.

Scientists discover an unexpected influence on dividing stem cells’ fate
When most cells divide, they simply make more of themselves. But stem cells, which are responsible for repairing or making new tissue, have a choice: They can generate more stem cells or differentiate into skin cells, liver cells, or virtually any of the body’s specialized cell types.

Human-pig hybrids might be unsettling. But they could save lives.
Scientists inject human stem cells into a pig blastocyst. A laser beam was used to perforate an opening to the outer membrane of the pig blastocyst to allow easy access of an injection needle delivering human iPS cells.
Hypoxia in primary tumors influences dormant DTCs that evade cancer therapy, study shows
In a first of its kind study, Mount Sinai researchers have discovered the conditions by which specific signals in primary tumors of head and neck and breast cancers, pre-program cancer cells to become dormant and evade chemotherapy after spreading. Their findings, published in the January 31, 2017 issue of Nature Cell Biology and featured on the cover, could lead to new drug development, treatment options and transform the way doctors care for cancer patients to treat metastatic disease.
Johns Hopkins researchers create mature cardiomyocytes in the laboratory from stem cells
Generating mature and viable heart muscle cells from human or other animal stem cells has proven difficult for biologists. Now, Johns Hopkins researchers report success in creating them in the laboratory by implanting stem cells taken from a healthy adult or one with a type of heart disease into newborn rat hearts.
Scientists create mature heart muscle cells from stem cells
The mature heart muscle cells were created by implanting stem cells from a healthy adult or one with a type of heart disease into newborn rat hearts. The host hearts then give biological signals and chemistry necessary for the implanted immature heart muscle cells to overcome a developmental blockage that usually stops growth.

Gene expression of pluripotency determinants is conserved between mammalian and planarian stem cells.
Freshwater planaria possess extreme regeneration capabilities mediated by abundant, pluripotent stem cells in adult animals. Although planaria emerged as an attractive in vivo model system for stem cell biology, gene expression in neoblasts has not been profiled comprehensively and it is unknown how molecular mechanisms for pluripotency in neoblasts relate to those in mammalian embryonic stem cells .
