The stromal cell-derived factor-1 (SDF-1) gene contains a common polymorphism, termed SDF1-3'A, in an evolutionarily conserved segment of the 3'-untranslated region (3'-UTR). We compared SDF-1 genotypes in patients diagnosed with lymphoid leukemias and lymphomas. Since the SDF1-3'A variant deletes the MspI restriction site, PCR-restriction fragment length polymorphism (RFLP) analysis was used f...

Tooth regeneration by cell delivery encounters translational hurdles. We hypothesized that anatomically correct teeth can regenerate in scaffolds without cell transplantation. Novel, anatomically shaped human molar scaffolds and rat incisor scaffolds were fabricated by 3D bioprinting from a hybrid of poly-epsilon-caprolactone and hydroxyapatite with 200-microm-diameter interconnecting microchan...

The genes encoding Slits and their Robo receptors are silenced in many types of cancer, including breast, suggesting a role for this signaling pathway in suppressing tumorigenesis. The molecular mechanism underlying these tumor-suppressive effects has not been delineated. Here, we show that loss of Slits, or their Robo1 receptor, in murine mammary gland or human breast carcinoma cells results i...

The problems of pathological diagnosis recurrent miscarriage are relevant in modern reproductive medicine. One the important molecular markers endometrium is progesterone-induced blocking factor, which induced by progesterone under influence activated lymphocytes and has an immunomodulatory effect on implantation characteristics endometrium. In process trophoblast invasion, a special role also ...

BACKGROUND AND PURPOSE Drainage after surgery is commonly used, and the contents are generally discarded as clinical waste. We analyzed closed suction drainage fluid from hip arthroplasty patients to determine whether any multipotent stem cells were present that could be used as a source of cells for tissue regeneration. METHODS Drainage fluid was obtained from 14 patients after hip arthropla...

The bone marrow stromal microenvironment that regulates normal hematopoiesis suffers during leukemia development and its treatment. In this study, we examined Multipotent Mesenchymal Stromal Cells (MMSCs) and fibroblast colony-forming units (CFU-F) derived from the Bone Marrow (BM) of 15 adult patients with acute lymphoblastic leukemia (ALL) before and after allogeneic hematopoietic stem cell t...

Pluripotent stem cell-derived human primordial germ cell-like cells (hPGCLCs) provide important opportunities to study primordial germ cells (PGCs). We robustly produced CD38+ hPGCLCs [∼43% of FACS-sorted embryoid body (EB) cells] from primed-state induced pluripotent stem cells (iPSCs) after a 72-hour transient incubation in the four chemical inhibitors (4i)-naïve reprogramming medium and show...
