Lung stem cell treatment for IPF

My dad has a fatal lung disease called IPF (idiopathic pulmonary fibrosis). The end stage symptoms are chest pain, depression, reduced lung function, disturbed sleep patterns, and becoming housebound. “Pulmonary Fibrosis is a disease marked by scarring in the lungs. Tissue deep in the lungs become thick, stiff and scarred. The scarring is called fibrosis. As the lung tissue becomes scarred it interferes with a persons ability to breathe.” Survival for most patients is less than 5 years. The lung doctor told us in December my dad has 12-18 months left which is also the time he denied my dad a lung transplant. My dad has wrote to me this on March 25th 2018 “I lost all hope when denied lung transplant now with the possibility of lung stem cell treatment I have been able to find some more hope again. My life right now is nothing more than being connected and dependent on a 50 ft hose for oxygen. Luckily I have you to make sure I get out every day and help me get in and out of home and vehicle to keep me with something to push forward for. I’ve never had to ask for help and I’m embarrassed to do so now. With the procedure I have a chance for more time with your momma (my wife of 47 years), my children, and my wonderful grandchildren who I so much want to see grow up as much as possible. I fear without this I won’t make it to see 2019. There are times breathing is almost impossible and to feel like I’m choking is very scary and a feeling I do longly pray to not keep feeling. I pray this will work even just a slight bit would be so much worth it for me. I love you. Dad.” Please help my dad with this last ounce of hope not only him but our family has for him right now. We know our time is precious and limited and to see him suffer is the worst and hardest thing to endure but even more so on him. Thank you all in advance for any prayers and help you are able to give. Please share with everyone you know the sooner he can get this stem cell treatment the better as each day is not promised.
