    Patient-specific embryonic stem cells derived from human SCNT blastocysts (2005)
    American Association for the Advancement of Science (AAAS)

    Publication Date: 2005-05-21
    Description: Patient-specific, immune-matched human embryonic stem cells (hESCs) are anticipated to be of great biomedical importance for studies of disease and development and to advance clinical deliberations regarding stem cell transplantation. Eleven hESC lines were established by somatic cell nuclear transfer (SCNT) of skin cells from patients with disease or injury into donated oocytes. These lines, nuclear transfer (NT)-hESCs, grown on human feeders from the same NT donor or from genetically unrelated individuals, were established at high rates, regardless of NT donor sex or age. NT-hESCs were pluripotent, chromosomally normal, and matched the NT patient's DNA. The major histocompatibility complex identity of each NT-hESC when compared to the patient's own showed immunological compatibility, which is important for eventual transplantation. With the generation of these NT-hESCs, evaluations of genetic and epigenetic stability can be made. Additional work remains to be done regarding the development of reliable directed differentiation and the elimination of remaining animal components. Before clinical use of these cells can occur, preclinical evidence is required to prove that transplantation of differentiated NT-hESCs can be safe, effective, and tolerated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hwang, Woo Suk -- Roh, Sung Il -- Lee, Byeong Chun -- Kang, Sung Keun -- Kwon, Dae Kee -- Kim, Sue -- Kim, Sun Jong -- Park, Sun Woo -- Kwon, Hee Sun -- Lee, Chang Kyu -- Lee, Jung Bok -- Kim, Jin Mee -- Ahn, Curie -- Paek, Sun Ha -- Chang, Sang Sik -- Koo, Jung Jin -- Yoon, Hyun Soo -- Hwang, Jung Hye -- Hwang, Youn Young -- Park, Ye Soo -- Oh, Sun Kyung -- Kim, Hee Sun -- Park, Jong Hyuk -- Moon, Shin Yong -- Schatten, Gerald -- New York, N.Y. -- Science. 2005 Jun 17;308(5729):1777-83.

    Synapse- and stimulus-specific local translation during long-term neuronal plasticity (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-05-16
    Description: Long-term memory and synaptic plasticity require changes in gene expression and yet can occur in a synapse-specific manner. Messenger RNA localization and regulated translation at synapses are thus critical for establishing synapse specificity. Using live-cell microscopy of photoconvertible fluorescent protein translational reporters, we directly visualized local translation at synapses during long-term facilitation of Aplysia sensory-motor synapses. Translation of the reporter required multiple applications of serotonin, was spatially restricted to stimulated synapses, was transcript- and stimulus-specific, and occurred during long-term facilitation but not during long-term depression of sensory-motor synapses. Translational regulation only occurred in the presence of a chemical synapse and required calcium signaling in the postsynaptic motor neuron. Thus, highly regulated local translation occurs at synapses during long-term plasticity and requires trans-synaptic signals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2821090/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2821090/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Dan Ohtan -- Kim, Sang Mok -- Zhao, Yali -- Hwang, Hongik -- Miura, Satoru K -- Sossin, Wayne S -- Martin, Kelsey C -- 15121/Canadian Institutes of Health Research/Canada -- NS045324/NS/NINDS NIH HHS/ -- R01 NS045324/NS/NINDS NIH HHS/ -- R01 NS045324-08A2/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2009 Jun 19;324(5934):1536-40. doi: 10.1126/science.1173205.
