A Canadian research team has developed an automated microfluidic cell culture platform to monitor the growth, survival and responses of hundreds of hematopoietic stem cells (HSCs) at the single cell level. This new tool allows scientists to study multiple temporally varying culture conditions simultaneously and to gain new insights on the growth factor requirements for HSC survival. "The ability to perform massively parallel cultures of single non-adherent mammalian cells will provide new...

The bone marrow stem cells responsible for generating new blood cells are less fixed and more flexible than previously thought, according to a paper published online on February 7 in the Journal of Experimental Medicine (www.jem.org). Some earlier studies suggested that these hematopoietic stem cells (HSCs) come in two distinct varieties: those that remain dormant during times of health but possess the ability to regenerate the whole blood system after trauma such as irradiation or...

(Ivanhoe Newswire) -- Platelets are cell fragments that circulate in the blood of mammals.  These big, regularly-shaped cells are chiefly involved in hemostasis, a central factor leading to the formation of blood clots.  If the number of platelets is too low, excessive bleeding can occur (thrombocytopenia).  However, if the number of platelets is too high, blood clots can form (thrombosis). Mortimer Poncz and colleagues, at Children's Hospital of Philadelphia, working with...

Researchers at the Burnham Institute for Medical Research (Burnham) have discovered that reactive oxygen species, such as superoxide and hydrogen peroxide, play a key role in forming invadopodia, cellular protrusions implicated in cancer cell migration and tumor metastasis. Sara Courtneidge, Ph.D., professor and director of the Tumor Microenvironment Program at Burnham's NCI-designated Cancer Center, and colleagues have found that inhibiting reactive oxygen reduces invadopodia formation and...

Paneth Cells
2012-07-01 19:03:07

Paneth Cells are one of four principal cell types found in the epithelium of the small intestine; the other three are the goblet cell, enterocyte, and enteroendocrine cell. Paneth cells may also be found in the cecum and appendix, although sporadically. These cells are identifiable microscopically by their location just below the intestinal stem cells in the intestinal glands. and the large eosinophilic refractile granules that occupy most of their cytoplasm. These granules consist of...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
