The stromal cell derived factor 1 (SDF-1/CXCL12) plays an essential role in the homing of hematopoietic stem and progenitor cells (HSPCs) to bone marrow (BM). It is not known whether SDF-1 may also regulate the homing of HSPCs to the liver during extramedullary hematopoiesis (EMH). Here, we investigated the possible role of SDF-1 in attracting HSPCs to the liver during experimental EMH induced by...
Cavernous hemangiomas are the most common lesion of the liver. Because of the risk of hemorrhage inherent in percutaneous biopsy of such lesions, noninterventional modalities (such as CT, ultrasound, MRI and Technetium-99m red blood cell imaging) have been utilized for differentiating them from other lesions. The sensitivities and specificities of these techniques vary greatly. Technetium-99m red...
