Apoptosis role of FAS/FAS ligand system in the regulation of myelopoiesis.

Objectives: CD34+ cells and colony forming unit-granulocyte and macrophage (CFU-GM) from human bone marrow were used to investigate the role of Fas/FasL system in the regulation of myelopoiesis.

Methods: Fas and FasL expression in CD34+ cells and in day 14 CFU-GM were measured by RT-PCR and immunofluorescence respectively. The functional assays for the CFU-GM were measured by a standard colony assay and the proliferative capacity of CFU-GM was measured by replating the primary colony and observing the secondary colony formation.

New trends in medical education. The clinical skills laboratories.

A clinical skills laboratory or center is a facility in which students, physicians, nurses and other health care professionals learn clinical, communication and information technology skills to a specified level of competence prior to or coordinated with direct patient contact. The purpose of the clinical skill laboratory is to support the acquisition, maintenance and enhancement of the clinical skills of students in health care professions. Within this non-threatening environment, patient volunteers, simulated patients, mannequins and information technology are employed to provide hands-on learning experiences for the practice of the essential clinical skills.
