this is an observational study, patients with gestational or pre-gestational diabetes undergoing elective (pre-labour) Cesarean section will be asked to participate in the study. Samples of placenta and umbilical cord will be taken postpartum and will be fixed and examined using immunohistochemistry to measure abundance of telocytes in these tissues. another group of patients with non complicated pregnancies will be asked to join as a control. As the topic was never studied before, a pilot phase of 10 patients per group will be done followed by sample size collection based on SD of number of telocytes in each group. Diabetes patients will divided in 3 subgroups; Gestational diabetes and pre-gestational diabetes type 1 or 2. Each group will be further subdivided according to HBA1C level collected at the time of delivery into controlled or non controlled.
