Figure 3. Effects of soy PG on keratinocyte proliferation.

Near-confluent keratinocytes were treated for 24 hrs with the indicated concentrations of soy PG liposomes, prepared via bath sonication of the phospholipid in SFKM. [³H]Thymidine incorporation into DNA was then determined as above. Values represent the means ± SEM of 5 separate experiments performed in duplicate; *p<0.05, **p<0.01 versus the control value (0 µg/). [³H]Thymidine incorporation into DNA in the control was 62,600±8,000 cpm/well.
