BACKGROUND High-dose chemotherapy followed by autologous stem cell transplantation is the standard treatment for relapsed and/or refractory Hodgkin's lymphoma although half of patients relapse after transplantation. Predictive factors, such as relapse within 12 months, Ann-Arbor stage at relapse, and relapse in previously irradiated fields are classically used to identify patients with poor out...

Objective- Investigate myocardial performance after autologous adipose-derived (ASCs) mesenchymal stem cell differentiated under equiaxial cyclic strain, transplantation in rabbits with acute myocardial infarction (AMI). Design- Prospective, randomized experimental study Animals- 20 New Zealand White rabbits (2-3 kg) P...

BACKGROUND Facial lipoatrophy, a common alteration among HIV-1-infected, antiretroviral-treated patients, is often corrected using autologous transplantation. In some cases, especially when enlarged adipose tissue from the dorso-cervical area (that is, a 'buffalo hump') is used as a source of fat for transplantation, the transplanted fat develops progressive hypertrophy. To gain insight into th...

To circumvent problems in fetal nigral and autologous adrenal transplants in parkinsonism, we have employed transplantation of the autologous cervical sympathetic ganglion containing noradrenergic and dopaminergic neurons. The synthetic meperidine analogue, MPTP (1-3 mg/kg, i.v.) was injected into ten monkeys (Macaca fuscata, weighing 3 to 6 kg) to produce experimental parkinsonism. Two to thre...

Patients with solid tumors are increasingly being treated by autologous bone marrow transplantation (BMT). Although response rates appear to be increased, disease recurrence is the commonest cause of treatment failure. Whether relapse is entirely due t o residual disease in the patient or arises also from infiltrating malignant cells contained in the autologous marrow transplant has not been re...

Autologous hematopoietic stem cell transplantation (HSCT) is a potentially curative therapeutic approach for various malignant hematologic and lymphoid diseases. Hematopoietic stem cells (HSCs) may be collected from the blood or the bone marrow. HSCs are capable of self-renewal and give rise to progenitor cells, multipotent cells that differentiate and proliferate into the mature cells of the b...

stem cells are undifferentiated biological cells that can differentiate into specialized cells and can divide (through mitosis) to produce more stem cells. they are found in multicellular organisms. in mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. in ad...
