- Lin28b Reprograms Adult Bone Marrow Hematopoietic Progenitors to Mediate Fetal-Like Lymphopoiesis
[作者:Yuan, J; Nguyen, CK; Liu, XH; Kanellopoulou, C; Muljo, SA,期刊:Science, 页码:1195-1200 , 文章类型: Article,,卷期:2012年335-6073]
- The immune system develops in waves during ontogeny; it is initially populated by cells generated from fetal hematopoietic stem cells (HSCs) and later by cells derived from adult HSCs. Remarkably, the genetic programs th...
- An Impactor Origin for Lunar Magnetic Anomalies
[作者:Wieczorek, MA; Weiss, BP; Stewart, ST,期刊:Science, 页码:1212-1215 , 文章类型: Article,,卷期:2012年335-6073]
- The Moon possesses strong magnetic anomalies that are enigmatic given the weak magnetism of lunar rocks. We show that the most prominent grouping of anomalies can be explained by highly magnetic extralunar materials from...
