An early stage embryo of about 100 cells that has not yet implanted into the womb. The blastocyst is a sphere made up of an outer layer of cells, a fluid-filled cavity and cluster of cells inside called the inner cell mass. The blastocyst develops after cleavage and prior to implantation at approximately five days. Further reproductive development occurs only if the blastocyst is successfully implanted in the uterus.

早期胚胎的约 100 单元格,已不能尚未植入子宫。胚囊是一个球体组成的外层细胞的一个充满液体的腔和群集内部细胞称为内细胞质量。胚囊开发后的乳沟和植入术在大约五天前。进一步只有胚泡成功植入子宫中,就会发生生殖发育。

A research study in human subjects to answer specific questions about vaccines or new therapies or new ways of using known treatments. Clinical trials are used to determine whether new drugs or treatments are both safe and effective. Trials take place in four phases: Phase I tests a new drug or treatment in a small group; Phase II expands the study to a larger group of people; Phase III expands the study to an even larger group of people; and Phase IV takes place after the drug or treatment has been licensed and marketed.
