Labor unions can increase wages through:
collective bargaining
Reducing supply of labor
and increasing demand for labor
In collective bargaining, the workers can send their representatives to negotiate new working terms with employers (including work hours and increasing wages).
Reducing supply of labor would make the existing laborers become more lucrative, rare and valued. This would resulted in an increase of workers' wages.,
Increasing demand for labor can be done by improving the members' skills through courses or seminar. By having additional skills, the members can be eligible to harder and more rare job opportunities. This usually correlate with higher wages

Answer:
<em><u>The answer is</u></em>: <u>They not only serve for Regenerative Medicine, but also for the "screening" of new drugs, and some other things.</u>
Explanation:
Currently, studies in regenerative medicine are aimed at research and knowledge of induced pluripotent cells (iPSCs). For some, they are the cells called to take over from embryonic stem cells (ESCs), which until recently were the main objective of research in this field of biomedicine.
<u>Since the first cultures of mouse embryonic cells derived from blastocysts were obtained in 1981</u>, the foundations were laid for the development of the necessary methodologies that would lead later to generate human embryonic cells with characteristics similar to those of the mouse.
In addition to their interest in Regenerative Medicine, these types of cells are a tool of great value for the "screening" of new drugs, as well as a model to study the etiology of diseases that originate during the embryonic stage, and to study processes that occur during human embryonic development
