PLATELET-DERIVED GROWTH FACTOR-C FUNCTIONS AS A GROWTH FACTOR IN MOUSE EMBRYONIC STEM CELLS AND HUMAN FIBROSARCOMA CELLS

Platelet-derived growth factor-C functions as a growth factor in mouse embryonic stem cells and human fibrosarcoma cells

Abstract Background Platelet-derived growth factor-C (PDGF-C) has been shown to be involved in several biological processes, such as embryonic development, wound healing and angiogenesis, as well as in diseases including tumor formation and fibrotic diseases.However, its role in fibrosarcoma and embryonic stem (ES) cells has not been elucidated.Met

A SAKF-Based Composed Control Method for Improving Low-Speed Performance and Stability Accuracy of Opto-Electric Servomechanism

The opto-electric servomechanism (OES) plays an important role in obtaining clear and stable images from airborne infrared detectors.However, the inherent torque disturbance and the noisy speed signal cause a significant decline in the inertial stability accuracy and low-speed performances of OESs.Traditional linear control schemes cannot deal with

Consolidity: Moving opposite to built-as-usual systems practices

With the recent uncovering Nightlight Globe of the mystery of consolidity as an inner property of systems, it is demonstrated that this notion is an indispensable pillar of systems modeling, analysis, design and building.Based on the opposite mathematical relation between consolidity versus stability and controllability, a new conceptual life cycle
