ABSTRACT
The anticipatory postural adjustments can be more precise in reflecting the ability of posture control,which associate with two kinds of neuromuscular model.Anticipatory postural adjustments disorders are found in stroke patients with hemiplegia,such as delay of muscle activation time,decrease of muscle activation,degradation of muscle recruitment order and reduction of adaptability.
ABSTRACT
In order to further study mouse embryonic stem cells(ES cells),lentiviral vector PLL-IRES-Nanog-Neo was constructed.Mouse ES cells overexpressed nanog by mediation of lentiviral were cultured on mouse fetal fibroblast feeders after 2 weeks under G418 media and examined according to gowth characteristics. Results were showed that 918 bp nanog fragments were expressed in mouse ES cells mediated by lentiviral vector PLL-IRES-Nanog-Neo,mouse nanog-ES cells were taken on mass-like image and positve with alkaline phosphatase staining and Oct4 and SSEA1 immunocytochemistry under no LIF condition in the media. It is concluded that mouse ES cells Elevated nanog gene expression by mediation of lentiviral were constucted and cultured.
