Xing Lab publish in Science Advances: Quantify cell phenotypic transition dynamics

In this work the Xing Lab tackled an outstanding open question on if and how one can extract dynamical information from snapshot data.
They first developed a quantitative framework that integrates standard imaging facilities and state-of-the-art computational analysis approaches to extract high-dimensional dynamical features of single live cell trajectories. The ability of being “quantitative” and “high-dimensional” is critical for addressing the question mentioned above. The framework allows one to use the same mathematical language to quantitatively describe cell phenotypic transition dynamics as one describes particle motions in physics and chemistry. This a conceptual novelty sets up a new framework of studying the biological processes from a physics perspective. They studied the epithelial-to-mesenchymal transition, and identified two parallel paths for the transition process that are concealed from snapshot data due to cell-cell heterogeneity. The work demonstrates the importance of live cell studies, and our developed framework provides such a general quantitative platform.

The recommended dose of kamagra 100mg oral jelly is three doses a day. For best results, men should not exceed the maximum daily dosage of five hundred milligrams. This medication should not be combined with any other prescription or over-the-counter medications, especially nitrate supplements or antibiotics. Also, men who are undergoing treatment for diabetes, hypertension, heart disease, or seizures should consult their physician before they consume this type of oral jelly. This medication should also not be used by women during their menstruation period. If you suspect that you might be allergic to sildenafil or any ingredients contained in this medication, talk to your doctor right away.
