The average grey values of collagen I and III, and GAPDH in the grafted skin on day 56 after transplantation (, n = 10)

Groups	Collagen I	Collagen III	Ratio between collagen I and III
HA1	848·38 ± 90·64 Δ , *	1637·37 ± 106·85 Δ , *	0·52
HA2	1874·68 ± 157·33 Δ , *	4874·17 ± 366·81 Δ , *	0·38
PADM	548·34 ± 42·98 *	877·35 ± 67·88	0·63
TS	1040·28 ± 45·78	81·37 ± 6·45	12·5
NS	1267·44 ± 61·82	795·64 ± 91·77	1·59
GAPDH	3235·58 ± 206·47

HA, hyaluronic acid; NS, normal skin; PADM, porcine acellular dermal matrix; TS, thin skin.

The PADM group shows significant differences compared with the HA1 and HA2 groups ( ^Δ P < 0·05) and the NS group shows significant differences compared with the HA1, HA2 and PADM groups ^*(P < 0·05).
