Human dermal fibroblasts obtained by skin biopsy can be reprogrammed directly to pluripotency by the ectopic expression of defined transcription factors. Here, we describe the derivation of induced pluripotent stem cells from CD34+ mobilized human peripheral blood cells using retroviral transduction of OCT4/SOX2/KLF4/MYC. Blood-derived human induced pluripotent stem cells are indistinguishable ...

Interstitial Cajal Cells (ICCs) were only proven in human adult hepatic tissue. The immune phenotypes of various cell types in the human embryonic liver (HEL) are scarcely described. It was hypothesized that in HEL ICCs are present and distinctive to the precursor/progenitor cells populations. It was aimed and performed a qualitative study of HEL by use of antibodies against CD117/c-kit, CD31, ...

A monoclonal hamster antibody (K-1) specific for a 161-kD mast cell surface glycoprotein was derived. p161 is expressed on normal and cultured mast cells and on some macrophages, but not on basophils or other hematopoietic cells. A population of Fc epsilon Rneg cells expressing p161 was found in short term cultures of bone marrow cells grown in interleukin (IL)-3. These cells were purified and ...

We previously reported a new approach for micromanipulation and encapsulation of human stem cells using droplet-based microfluidic device. This demonstrated the possibility encapsulating culturing difficult-to-preserve primary hematopoietic an engineered double-layered bead composed by inner layer alginate outer Puramatrix. also maintenance expansion Multiple Myeloma in this construction. Here,...

Bone marrow was isolated from a child with congenital mastocytosis. Upon prolonged in vitro culture, initially in the presence of interleukin-3 (IL-3), a population of relatively large fusiform, strongly adherent cells grew out plus a subpopulation of smaller nonadherent cells. The morphology of the adherent cells was not typical of fibroblasts, epithelial cells, nor of standard hematopoietic c...

Human embryonic stem (ES) cells are undifferentiated, pluripotent cells that can be maintained indefinitely in culture. Here we demonstrate that human ES cells differentiate to hematopoietic precursor cells when cocultured with the murine bone marrow cell line S17 or the yolk sac endothelial cell line C166. This hematopoietic differentiation requires fetal bovine serum, but no other exogenous c...

Adrenal myelolipoma is a rare benign tumor that is composed of hematopoietic cells and mature fat. Mostly, these nonfunctioning tumors are distinguished incidentally during autopsy or radiologic investigations. Here, we report a case of 46-year-old man presented with nonspecific abdominal pain for one year, who had right adrenal mass with fat density detected by radiologic investigation. Histop...

Umbilical cord blood is the baby's blood left over in the umbilical cord and placenta after a baby is delivered and the cord is cut. Cord blood has all of the features of regular blood, but it is also a rich source of hematopoietic stem cells. Hematopoietic stem cells are unspecialized cells that produce all blood cells. These include: • Platelets, which are needed for blood clotting • Red...
