Chemotaxis and phagocytosis in anucleated cytoplasmic fragments of human peripheral blood leucocytes. 1975

H U Keller, and M Bessis

Viable anucleated fragments of hyaloplasm were obtained by heating human blood leucocytes. These anucleated cytoplasmic fragments exhibited random migration, chemotaxis (necrotaxis) toward red cells which had been destroyed by a laser beam and they were capable to ingest heat-killed Staph. albus.

UI	MeSH Term	Description	Entries
D007834	Lasers	An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.
