DNA ligase IV deficiency syndrome (LIG4 syndrome) is a rare autosomal recessive disorder characterized by microcephaly, growth retardation, low birth weight, dysmorphic facial findings, immunodeficiency, pancytopenia, and radiosensitivity due to impaired repair of DNA double-strand breaks by non-homologous end-joining. Herein, we report two siblings with(More)
Mesenchymal stem cells (MSCs) are one of the most studied adult stem cells and in recent years. They have become attractive agents/cell source for cellular therapy and regenerative medicine applications. During investigations about their origin, researchers hypothesized that perivascular regions are the common anatomical regions where MSCs come from and(More)
OBJECTIVE Angiogenesis have implications in leukemia biology. Angiopoietin 1 (Ang 1) is an angiogenic cytokine which is essential in survival and proliferation of endothelial cells. Angiopoietin 2 (Ang 2) promotes dissociation of pericytes and increases vascular permeability and stromal derived factor 1 alpha (SDF 1α) which is a key player in stem cell(More)
We hypothesized that the individual hematological response to chemo/ radiotherapy may be used as a parameter to assess the degree of myeloablation and probability of transplant-related events. This study included 58 pediatric patients who underwent allogeneic hematopoietic stem cell transplantation (HSCT). White blood cell (WBC) ratio (pre-conditioning WBC:(More)
