Latar Belakang: Meningkatnya angka kejadian stroke dan beratnya disabilitas dari penderita stroke yang bertahan hidup, menjadikan diperlukannya terapi yang optimal untuk restorasi paska stroke. Neurorestorasi dengan transplantasi sel punca menjanjikan perbaikan luaran fungsional yang baik pada pasien stroke iskemik. Penelitian ini dibuat untuk mengamati efek transplantasi Stem Cell from Human Exfoliated Deciduous Teeth SHED pada luaran klinis dan rasio sel neuron mati pada model stroke iskemik, untuk mendapatkan terapi yang optimal untuk stroke iskemik. Metode: Pembuatan tikus model stroke iskemik dilakukan dengan oklusi arteri cerebri media (MCAO). Pada 48 jam setelah MCAO, dilakukan transplantasi sel mesenkimal asal SHED secara intravena, dengan dosis 2x106/kgBB. Dilakukan evaluasi fungsional tikus secara neurobehaviour dengan tes Y Maze, dan evaluasi sensorimotor tikus dengan tes silinder. Evaluasi rasio neuron mati dilakukan dengan pewarnaan Hematoksilin dan Eosin. Hasil: Terdapat perbaikan evaluasi neurobehaviour dengan Y Maze (p=0,04) dan evaluasi sensorimotor dengan tes silinder (p=0,04) pada 14 hari setelah transplantasi pada kelompok tikus yang ditransplantasi SHED dibandingkan kontrol. Terdapat pengurangan rasio sel neuron mati (p=0,0) pada tikus yang ditransplantasi SHED pada 21 hari setelah MCAO. Kesimpulan: Transplantasi SHED pada tikus model stroke iskemik pada fase akut stroke menunjukkan perbaikan klinis dan terdapat pengurangan rasio neuron mati pada otak tikus model stroke iskemik yang di transplantasi dengan sel mesenkimal asal SHED.
Background: The incidence of stroke reaches 15 million cases worldwide, and 5 million stroke survivors suffered permanent disability. Ischemic stroke causes a burden on health problems particularly in Indonesia. The prevalence of stroke in Indonesia in 2013 is 7 per 1000 population. The optimal stroke restoration therapy required, and neurorestoration with stem cell transplantation is a promising therapy that provides functional improvements for ischemic stroke. This research was conducted to observe the effects of Stem Cell from Human Exfoliated Deciduous Teeth (SHED) transplantation on the clinical improvement and neuron death ratio in the brain of rats models with ischemic stroke. Methods: One group of normal rats and two groups (n=5) of male wistar rats undergone permenents Middle Cerebral Artery Occlusion (MCAO). SHED transplantation performed 48 hours after MCAO, by intravenous injection with a dose of 2x106 cells/kg. Functional evaluation conducted in rats with Y Maze and cylinder Test. Evaluation of the death neurons ratio in brain cortex area done by Hematoksilin and Eosin staining.Results : The functional evaluation using Y Maze and Cylinder Test was significantly improved in the treatment group compared to the control stroke group p < 0,05 14 days after MCAO. There was a reduction in the neuron death ratio p = 0.0 in rats transplanted with SHED.Conclusion : SHED transplantation in acute stroke showed clinical improvement and reduction in the neuron death ratio in the brain of rat models with ischemic stroke. Keywords: Cell transplantation, Ischemic Stroke, MCAO, SHED

Advances in stem cell research discusses recent advances in stem cell science, including therapeutic applications. This volume covers such topics as biomanufacturing iPS cells for therapeutic applications, techniques for controlling stem cell fate decisions, as well as current basic research in such areas as germ line stem cells, genomics and proteomics in stem cell research.

Abstrak :
Vast therapeutic applications of the following specific stem cells in disease and tissue injury are discussed, embryonic stem cells, induced pluripotent stem cells, human hair follicle stem cells, bone marrow-derived human mesenchymal stem cells, adipose-derived stem cells, periodontal/progenitor cells, cancer stem cells, and breast cancer stem cells. Because human embryonic stem cells possess the potential to produce unlimited quantities of any human cell type, considerable focus is placed on this type of stem cells in this volume. The role of cancer stem cells, specifically in breast cancer is explained. Transplantation of mesenchymal stem cells to aid the injured brain is included. Immune recovery after stem cells transplantation in severe combined immunodeficiency patients is described. The role of mesenchymal stem cells in enhancing the growth and metastasis of colon cancer is discussed. Clinical application of human follicle stem cells is presented. Treatment of malignant gliomas using genetically-modified neural stem cells as a marker is discussed. The impact of cancer stem cell hypothesis on designing new cancer therapies is explained. In the field of regenerative medicine, the use of stem cells in the repair of the central nervous system, tendon injury, and as a cardiac regenerative medicine is described. The role of DNA methylation in maintaining stemness induced pluripotent stem cells from human extraembryonic amnion cells is discussed. Insights on the understanding of molecular pathways involved in tumor biology are explained, which lead to the development of effective drugs. Information on pathways, such as hedgehog, facilitates targeted therapies in cancer.

[This volume will cover a series of reviews on stem cells including adult and embryonic stem cells. Speakers were invited to present these talks during the Stem Cell Symposia in fall of 2010, in Samsun, Turkey. Unique aspect of this volume is that it brings a multidisciplinary aspect of stem cells extracted from a symposium., This volume will cover a series of reviews on stem cells including adult and embryonic stem cells.
