How are target cells formed
WebA target cell responds to a hormone because it bears receptors for the hormone. In other words, a particular cell is a target cell for a hormone if it contains functional receptors for that hormone, and cells which do not have such a receptor cannot be influenced directly by that hormone. Reception of a radio broadcast provides a good analogy. WebTarget cells are labeled by incubating 100 μCi of labeled sodium chromate (51 CrNa2CrO4; Amersham, Arlington Heights, IL) with 2 × 10 6 cells in 0.5 ml of RPMI 1640–10% (v/v) FCS at 37° for 1 hr. Lymphoid target cells such as YAC-1, Jurkat, etc., are good targets for this assay. The labeled cells are washed three times with cold HBSS and ...
