ABSTRACT
<p><b>OBJECTIVE</b>To explore the prophylactic effect of tissue inhibitor of matrix metalloproteinase (TIMP) on acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in a murine model.</p><p><b>METHODS</b>The murine model of aGVHD after allo-HSCT was established by using female C57BL/b (H-2b) mouse as the donor, and male BALB/c (H-2b) as the recipient. After allo-HSCT, recipient mice were divided into 3 groups. For aGVHD prophylaxis group A was given TIMP (2 mg/d) , group B CsA (5 mg x kg(-1) x d (-1)) was given, and group C nothing. Physical signs, mean survival time (MST), peripheral blood counts and aGVHD histopathology were observed.</p><p><b>RESULTS</b>Mice in group C developed typical aGVHD and 100% of mortality, with a MST of 8 days, and those in group A and B had longer survival, the MST being (4.8 +/- 1.4) d and (4.3 +/- 0.9) d respectively, with no statistical difference in peripheral blood count between these two groups. Mice in group A showed less severe signs.</p><p><b>CONCLUSIONS</b>TIMP markedly prolongs MST of allo-HSCT recipients, delays the onset of aGVHD signs, and has no adverse effect on hematopoiesis reconstitution.</p>
