| Origin of Peptide | Synthetic |
| Nature of Peptide/Cargo | It induces a moderate but long-lasting inhibition of epidermal cell proliferation when given at low (picomol) doses but stimulates epidermal cell proliferation at higher doses |
| Mechanism | It induces long-lasting oscillations in the epidermal mitotic rate and DNA synthesis. |
| Cargo Sequence/Structure | None |

| Assay | Colcemid-arrested mitoses and labelled cells were counted per 12 mm of interfollicular epidermis in 5 pm paraffin sections stationed with haematoxylin in the former and dipcoated with NTB 2 emulsion and incubated for 3 weeks at 0-4 ͦC for later. The statistical evaluations were made according to the Wilcoxon's rank sum test. |
| Enhancer | None |
| Properties of enhancer | Not applicable |
| Concentration | 0.25 (wt/wt) EPP cream |
| Incubation time | 30 minutes |
| Tissue permeability (value with units) | The mitotic rate was strongly increased with peaks at days 1, 3 and 6 (twice the control value). |
| Tissue Sample | Back skin of female hairless mice (hr/hr) |
| Ex vivo/In vivo/In vitro | in vivo |
