Abstract: Disclosed are a shingled cell, a cell unit, and a shingled photovoltaic assembly. The cell unit includes a cell. The front side of the cell includes a plurality of parallel front-side fine grid lines. The back side of the cell includes a plurality of parallel back-side fine grid lines and a front-side connection line. The front-side connection line is a continuous or non-continuous line segment. The front-side connection line is arranged on at least one side of the cell. The front-side connection line is connected to the ends of all the front-side fine grid lines on the same side. The front-side connection line is such configured that when two cell units are overlapped along the extension direction of the front-side fine grid lines, the front-side connection line of the lower cell unit contacts each of the back-side fine grid lines of the upper cell unit.

Abstract: An exosome active formulation for inhibiting endothelial cell migration, and a preparation method and use thereof include the following steps: isolating primary umbilical vein endothelial cells and performing cell culture and passage; adding anisodamine to a culture medium of the subcultured endothelial cells to pretreat the endothelial cells, and then replacing the culture medium with a new endothelial cell culture medium and adding TNF-? to continue the culture of the endothelial cells; extracting exosomes from the TNF-? containing endothelial cell culture medium obtained after the endothelial cells are cultivated; and identifying the exosomes. The exosome active formulation for inhibiting endothelial cell migration prepared by the preparation method of this disclosure and its use in the antitumor drugs.
