Adult stem cells are unspecialized cells with the capacity to differentiate into many different cell types in the body. These cells together with the progenitor cells involve in the tissue repair processes and maintain the functionality of the tissue in which they are found.

Cryopreservation of islets of Langerhans
Cryobiology, 1981Abstract Development of techniques for cryopreservation of pancreatic islets of Langerhans could potentially allow for increased freedom from the time restrictions presently affecting viability in islet cell transplantation. While several investigators have attempted islet cell freezing and have obtained favorable in vitro results after thawing ...

Proiactin Binding in Rat Langerhans Islets
Journal of Receptor Research, 1980Membrane preparations of collagenase-dispersed Langerhans islets of female Wistar rats exhibit specific binding sites for 125I-labelled ovine prolactin (125I-oPrl). Almost negligible binding was detected in islets of male animals. The binding is a saturable and time-temperature dependent process, equilibrium being reached after 16 h incubation at 0 ...

Glucoreceptor Mechanisms in Islets of Langerhans
Diabetes, 1972A widely accepted concept has been that metabolites of glucose or factors associated with glucose metabolism, rather than glucose itself, trigger insulin release from the β cells. If this concept is correct, levels of metabolites or cofactors or of both should change within seconds of the glucose pulse.

Vitrification of human islets of Langerhans
Cryobiology, 1987Cryopreservation of human islets of Langerhans by vitrification was studied. Isolated islets were divided into four groups: (1) control islets which were cultured for 6 days, (2) islets which were vitrified after 2 days of culture, (3) control islets which were cultured for 10-13 days, and (4) islets which were vitrified after 6-9 days of culture ...

Paracrine Interactions Within Islets of Langerhans
Journal of Molecular Neuroscience, 2012Glucose supply fluctuates between meal and fasting periods and its consumption by the body varies greatly depending on bodily metabolism. Pancreatic islets of Langerhans secrete various endocrine hormones including insulin and glucagon to keep blood glucose level relatively constant.
