Role of Stem Cells in Improving Implantation Rates in ICSI Patients
Phase I Study of Role of Stem Cells in Improving Implantation Rates in ICSI Patients

Background:

Improving implantation rates in ICSI cycles has been the focus of research in recent decades. Because success rates is not satisfactory enough especially when transferring good embryos to the uterine cavity and pregnancy does not occur. Trying to improve endometrial receptivity, the investigators have thought about stem cell therapy as stem cells have played a pivotal role in regenerative medicine in many pathologies as myocardial infarction, Diabetes Mellitus and spinal cord injuries.

Garget and Healy reported in 2011 treatment of a case with Asherman's syndrome by administration of bone marrow stem cells in the uterine cavity. Endometrial growth and improved vascularity has been observed by ultrasound follow-up and Doppler study of endometrial blood flow. Endometrial regeneration has been enough to support pregnancy through successful IVF trial.

The investigators have succeeded in previous work to isolate MSC from placental tissue and differentiate it to endometrium-like cells. The investigators compared the differentiation ability of placental derived mesenchymal stem cells (MSC) and Wharton Jelly derived MSC to differentiate to endometrium under 3 different culture conditions: endometrium conditioned medium (ECM), follicular fluid (FF) conditioned medium and medium containing both. The investigators found that placental MSC has better differentiating ability to endometrium especially under culture conditions containing both ECM and FF as evidenced by prominent appearance of glandular pattern and expression of progesterone receptors in differentiated cells.

Therefore the investigators need to direct this study and test the effect of placental derived MSC in improving implantation rates in patients with recurrent implantation failure, unresponsive endometrium to ovulation induction drugs or with endometrial atrophy or advanced maternal age planning for ICSI trial.

Patients and Methods:

60 patients attending Kasr El-Aini assisted reproduction unit and private IVF center will be randomized to three groups by computer generated programs:

The first group, patients randomized to receive differentiated stem cell therapy:

After ovum pick-up, MSC differentiated to endometrium is deposited in the uterine cavity through an IUI catheter. Embryo transfer will be done at day 5 at the blastocyst stage to allow enough time for endometrial regeneration and increased endometrial receptivity.

The second group, patients randomized to receive undifferentiated stem cell therapy:

Immediately postmenstrual undifferentiated MSC is deposited in the uterine cavity through an IUI catheter to allow enough time for the MSC to differentiate as it needs 7-10 days for differentiation. Ovum pick-up will be done as usual while all other steps will be the same including embryo transfer which will be done at day 5.

The third group, control group:

Patients are randomized to receive no stem cell therapy; All ICSI steps from ovulation induction protocol to embryo transfer conditions will be the same for all groups.

Informed consent will be taken from the patients after detailed explanation of all steps of the procedure.
