Fig.2-3. Quantitation of A2B5(+) cells when unpurified and purified at the time of separation and after one day in culture. The unpurified cells show a small but significant increase in the number of A2B5(+) cells after one day. The purified cells are initially almost entirely A2B5(-), but after one day contain the same number of A2B5(+) cells as unpurified cultures. Shown are means s.e.m. for 4 individual experiments.
