cystic fibrosis and criopreservation umbilical cord blood and tissue

We have a daughter of 10 months with cystic fibrosis (mutations F508del and N1303K). She was diagnosed at 5 months after 4 admissions. We saved (criopreservation) the stem cells of tissue and blood of umbilical cord of our daughter, and we still saved the umbilical cord blood of our son, older (does not carry the defective gene, he is healthy). Anyone know or can clarify me the following issues: 1. We can use the steam cells of tissue or cord blood of our daughter with healing perspectives? 2. And the brother’s umbilical cord blood? 3. Me and my husband we are 'A Rh positive' as my son, but my daughter is 'A Rh negative', there are any chance of incompatibility between the brothers? 4. We would also like to know specifically if the umbilical cord blood and stem cells can help my daughter? 5. you know some place / country where this type of treatment is being done? in my country doctors do not want to know these subjects. Thank you in advance for your answer a desperate and worried mother tania
