We report the case of premature infant born at 32 weeks' gestation with a sacrococcygeal teratoma diagnosed in utero. During delivery by cesarean section, profound bleeding due to rupture of the teratoma occurred. Despite volume expansion with saline, albumin, and whole blood, a satisfactory
Carcinosarcoma is a rare form of ovarian cancer with mixed origin, and its association with mature teratoma is extremely rare. We present the case of patient T. M. aged 67, admitted into our clinic on the 15/05/2016, F.O. 4877 for the increase of the abdominal volume. On admission, the patient was
Extrahepatic neoplasms metastatic to the liver histologically are often indistinguishable from hepatocellular carcinoma (HCC). The differential diagnosis between HCC and metastatic liver tumours can be even more difficult in ultrasound guided fine-needle biopsies. Purpose of the present study was to
Human embryonic stem cells are pluripotent cells that can serve as a cell source for transplantation medicine, and as a tool to study human embryogenesis. We investigate here the potential of human embryonic stem cells to differentiate into hepatic cells. We have characterized the expression level
Serum levels of alpha-fetoprotein were determined in 33 patients with testicular germ cell tumors and were normal in 11 patients with seminoma and in one patient with matured teratoma; high levels were observed in 19 of 21 patients with embryonal carcinoma, teratocarcinoma, or a mixed type of these
Directed endodermal differentiation of murine embryonic stem (ES) cells gives rise to a subset of cells with a hepatic phenotype. Such ES cell-derived hepatic progenitor cells (ES-HPC) can acquire features of hepatocytes in vitro, but fail to form substantial hepatocyte clusters in vivo. In this
Human embryonic stem (hES) cells have unique features including unlimited growth capacity, expression of specific markers, normal karyotypes and an ability to differentiate. Many investigators have tried to use hES cells for cell-based therapy, but there is little information about the properties of
Hepatocytes can be generated from embryonic stem cells (ESCs) using inducers such as chemical compounds and cytokines, but issues related to low differentiation efficiencies remain to be resolved. Recent work has shown that overexpression of lineage-specific transcription factors can directly cause
Human embryonic stem cells (hESCs) are pluripotent cells that have the potential to differentiate into any tissue in the human body; therefore, they are a valuable resource for regenerative medicine, drug screening, and developmental studies. However, the clinical application of hESCs is hampered by
ESCs are a potential cell source for cell therapy. However, there is no evidence that cell transplantation using ESC-derived hepatocytes is therapeutically effective. The main objective of this study was to assess the therapeutic efficacy of the transplantation of ESC-derived endodermal cells into a
Anti-N-methyl-D-aspartate receptor (NMDA-R) encephalitis is thought to be one of the common paraneoplastic-associated encephalitides. Between February 2001 and February 2011, nine patients were diagnosed with this disorder at Columbia University Medical Center: eight females (mean age 23 years) and

Liver fibrosis results from the wound healing response to chronic liver damage. Advanced liver fibrosis results in cirrhosis and liver failure, and liver transplantation is often the only option for effective therapy; however, the shortage of available donor livers limits this treatment.
BACKGROUD/AIM: Because of the oncogenic risk, it is important to gain the homogeneous and purified cells from differentiated ESCs before transplantation. Here, we aim to select hepatocyte-like cells from differentiated ESCs, and investigate their growth, differentiation and neoplastic formation
We herein report a novel mechanism of action of statin preparations using a new drug discovery method. Milk fat globule-EGF factor 8 protein (MFG-E8) was identified from the secretory component of mouse embryonic fibroblast (MEF) as a cell adhesion-promoting factor effective for screening active
We previously reported that embryoid body (EB) cells derived from embryonic stem (ES) cells are capable of differentiating into functional hepatocyte-like cells both in vitro and in vivo. Because transplantation of EB-derived cells into the liver via the spleen resulted in a low incidence of
