|ISMTR-283 Protects Human Bone Marrow Progenitors from the Lethal Effects of Ionizing Radiation|
Clarke E, Traynor-Kaplan A
Bone Marrow (BM) is extremely susceptible to radiation damage. BM from matched donors is often used to ‘rescue’ patients following medical radiation for leukemia. However, in the event of accidental/environmental radiation exposure, the ability to identify appropriate donors in a timely manner is rarely possible. Using CFC assays, we evaluated a small molecule compound (ISMTR-283) for its potential to protect the marrow progenitor cells and microenvironment from radiation damage.
|Analyzing Molecular Polar Surface Descriptors to Predict Blood-Brain Barrier Permeation|
Sergey Shityakova, Winfried Neuhausa, Thomas Dandekarc and Carola Förstera
Permeation of active drugs across the vascular brain endothelium into the central nervous system (CNS) is controlled by the blood-brain barrier (BBB). Some molecular quantities like polar surface (PS) descriptors are of key interest to medicinal chemists to predict the BBB permeation fate for different drug-like chemical compounds.
|The Mesenchymal Stem Cells Bioengineered Tissue Using Cobalt-60 Radiation|
Mosca, RC., Isaac, C., Mathor, MB
The biological effects of gamma radiation by cobalt-60 sources on epidermal-dermal matrix have not been fully elucidated when mesenchymal stem cells cultured add in. This poster shows how scientists standardized the keratinocytes and adipose-derived stem cell (ADSC) culture procedure before constructing a bioengineered dermal-epidermal equivalent populated by keratinocytes and ADSC cultured cells.
|Expression of Pluripotency-determining Factors in in vitro Fertilized Buffalo Embryos and Embryonic Stem Cells|
T Anand, D Kumar, M S Chauhan, and P Palta
The POU octamer-binding domain transcription factor Oct-4, Stage-specific embryonic antigens (SSEAs), and Tumor rejection antigens (TRAs), are developmentally regulated during early embryogenesis.
|Effect of Culture Media and Serum Supplementation on the Development of in vitro Fertilized Buffalo Embryos|
D Kumar, T Anand, P Palta and M.S. Chauhan
This poster compares the development of buffalo embryos in simple and complex culture media and aims to determine the effects of serum supplementation on the development of buffalo embryos.
|High Content Analysis of Neural Stem Cell Expansion and Differentiation|
Oksana Sirenko, Allan C. Powe, Steven L. Stice, Karen Cook, Nick Callamaras, Jayne Hesley, Xin Jiang and Evan F. Cromwell
Automated assay methods for monitoring neural stem cell expansion and differentiation using stem cell derived neural cell lines and high content imaging systems have been described.
|Neurotoxicity Assays Using iPSC-Derived Neurons and High Content Imaging|
Oksana Sirenko, Susan DeLaura, Lucas Chase, Jayne Hesley and Evan F. Cromwell
Neurotoxicity can cause temporary or permanent damage of brain or peripheral nervous system and has been found to be a major cause of neurodegenerative diseases such as Alzheimer’s or Parkinson’s. Accordingly, there is a great interest in developing more predictive, disease relevant cell-based models and efficient screening tools for assessing the neurotoxicity of chemical compounds, drug candidates and environmental agents.
|Live Cell Beating Assay Using Human iPSC-derived Cardiomyocytes for Evaluation of Drug Efficacy and Toxicity|
Oksana Sirenko, Carole Crittenden, Blake Anson, Jayne Hesley, Yen-Wen Chen, Nick Callamaras and Evan F. Cromwell
A large percentage of new drugs fail in clinical studies due to cardiac toxicity. Development of highly predictive in vitro assays suitable for screening, safety assessment or other environments is therefore extremely important for drug development. Human cardiomyocytes derived from stem cell sources can greatly accelerate the discovery of cardiac drugs and improve drug safety by offering more clinically relevant cell-based models than those presently available.
|Regulation of shoot apical meristem development by SEUSS and SEUSS-LIKE 2 in Arabidopsis|
Joanne E. Lee and John F. Golz
In Arabidopsis, SEU and SLK2 are redundant components of a regulatory complex that is proposed to promote shoot apical meristem (SAM) formation during embryogenesis. Expression analysis indicates that SEU and SLK2 act upstream of several known SAM regulators, and also regulate auxin accumulation, probably via interaction with auxin response factors.
