TNC and SPARC mRNA Levels by Microarray in Response to Mechanical Stretch, TNFα, and IL-1α Treatment for 12, 24, and 48 Hours

	12 h	24 h	48 h
Tenascin C
Mechanical stretch	2.59	1.924	1.5
TNFα	3.67	4.22	NS
IL-1α	3.69	2.96	2.61
SPARC
Mechanical stretch	1.68	1.964	2.417
TNFα	NS	1.57	1.53
IL-1α	NS	NS	0.48

Numbers represent fold change from untreated control. Mechanical stretch values were previously published.¹³ NS, no significant change.
