Numbers of in vitro regenerating colonies depend on EXTL3 expression and endometriosis serum.

Diagnosis	Serum ID	EGFP	EXTL3-EGFPa
Endometriosis	E297	21	644
	E319	26	682
	E344	223	624
	E355	44	462
Infertile, no endometriosis	E353		35
	E356		18
	E358		54

^aOn average 78 (EGFP) vs 603 (EXTL3-EGFP) colonies grew with endometriosis patients’ sera; both n = 4, t-test, one tailed p = 0.002; and 35 (infertile patient sera, n = 3) vs 603 (endometriosis patient sera, n = 4) for EXTL3-EGFP transfected cells, t-test, one tailed, p = 9.5 × 10⁻⁵.
