Your written English is fine.Regenerative medicine caught my particular attention when I was studying at the University. In that time I was interested in gerontology and anti-aging therapies. Among various developing methods of resisting age-related diseases, regenerative technologies seemed to me the most perspective for achieving this goal since they can renew the human body, not simply conserve it. While I was studying scientific articles and reviews ontheregenerative medicine, iPSCs attracted my attention most of all. It was due to my long-term interest in cell biology, but what's more the possibility to reprogram cells impressed me. It opens a vast space for a great variety of experiments. iPSCs are used for a wide specter (spectrum?) of tasks, not only for therapy, but also for disease modeling and for drugsdevelopment. Though numerous things [factors/aspects. 'Things' is not a good word in academia] are still to be revealed. That is why I intend to study iPSCs in my future scientific work.
Iapply[am applying / have applied] for NNN PhD program as it perfectly meets my expectations. Several years ago I was already dreamingto workof working in a laboratorycluster[?] concentrated on studies in the field of regenerative medicine. This program attracts me by its rich contentallowing towhich would allow me to expand my knowledge and improve my practical skills. Another important point for me is that NNN unites diverse research groups. So Iwillwould [You don't have the job yet] be able to communicate with different researchers, learn what problems they are solving and what they have discovered, thereby extending my own understanding of the situation. I believe that dialogue between various research fields is essential for the overall progress.
My intention is to perform studies towards the Ph.D. [often simply PhD these days - I'd suggest you check and use the format the university uses; besides, you need to be consistant with the above] degree and afterwards to continue scientific researchesat a postdoctoral [It's a formal letter] position.
