      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: Randomization will be based on the block randomization method. Randomization will be done by a web software (https://www.sealedenvelope.com/simple-randomiser/v1/lists). The number of patients required per group (based on sample size determination) was estimated 12 patients per group (24 patients totally). Therefore, considering three random block sizes (4, 6 and 8), we will define blocks for randomization of patients. It is worth noting that random block design in the mentioned web software will be done by another researcher who is not involved in the process of sampling and following up patients. The patient assignment sequence to the study groups is only available to the researcher, and at the time of each patient's visit to the treatment center, the sampling physician will make a phone call to the randomized design researcher to get the patient in the right group. It is worth noting that the groups will be named Group A and Group B, and the physicians involved in the treatment and follow-up of patients will not be aware of the group's original name, Blinding description: Patients are given code. The patient is blind to the study (he/she does not know whether receives cell or placebo). An endoscopic expert who injects cell suspension  or the liquid in which the cell is suspended by endoscopy is blind to the study. The researcher (collector of data during post-intervention follow-up) is blind to the study.</study_design>
