What is a Stem Cell?

Stem cells are precursor cells designed to be stimulated by the body’s need to heal and revitalize aging or damaged tissue. Distributed throughout our bodies, stem cells reside in a resting state, awaiting signals to “awaken” and begin the process of tissue regeneration. These unique cells send signals to nearby tissues to reduce inflammation, promote healing and repair tissue. We naturally use these cells throughout our lives to replenish damaged areas and keep ourselves functioning properly. Stem cells are also capable of “turning into” tissues of various types when the body sends out biochemical messages. Their role in our health is to aid in the regeneration and growth of damaged or aging structures. They serve this function throughout our lives.

Adult stem cells are distributed throughout the body tissues in relatively modest numbers. We are now able to collect these cells and concentrate them into large numbers, which allow us to administer stem cells directly into tissues in need of repair.

Infusion of one’s own (“autologous”) stem cells is often used in certain cancer patients to successfully regenerate bone marrow blood and immune cells after chemotherapy has been administered.

Many newer applications of stem cell therapies are emerging for the treatment of a number of conditions. At Integrative Rheumatology of Westchester, we offer stem cell therapy for the treatment of arthritis and related musculoskeletal conditions, autoimmune diseases such as rheumatoid arthritis and multiple sclerosis. We are enrolled in an IRB and FDA-approved clinical research program, affiliated with the Cell Surgical Network® using standard protocols registered with CDC.gov.

Our process involves harvesting cells from the “stromal vascular fraction” of adipose tissue in order to deliver the cells throughout the body (systemically) or locally to affected tissue. The stromal vascular fraction contains numerous cell types, including mesenchymal stem cells, immunomodulatory, and tissue progenitor cells. This gives the patient the opportunity to use their own cells, now optimally directed, to heal a damaged body part or organ system. Many patients who are facing the possibility of surgery, including joint replacements may be candidates for Stem Cell joint therapy as a surgical alternative.

What our patients say

  • I have relied upon the medical skills of Dr David Lans since 2013 after a long search to find someone who could help me with my immune system problems.  Dr Lans offers a warm and inviting environment where you can unhurriedly discuss your problems and participate in proposed solutions.  I recommend him highly to my friends

  • Dr. Lans is indeed an amazing Doctor. On my first visit, he was kind caring and patient. He answered all my questions and asked me questions about my problems and how we could fix them. He didn't rush through my visit and was very thorough. Dr. Lans is a rare find. He is a very warm and genuine Doctor. I would give him 10 stars if I could! I wish I could still see him as my Doctor but he no longer accepts my insurance. Dr. Lans is Wonderful, Amazing, Caring, and Intelligent! Just a Great Doctor indeed!

  • I can’t say enough about how wonderful and professional Dr. David Lans is. I have been having trouble with my ankle since last November. In that time I have had three MRI’s and been to four different doctors. The last option was to have surgery. I was referred to Dr. Lans and traveled to New York to have a stem cell procedure done. Dr. Lans explained to me every step of the way what was going to happen and what I would be feeling and helped me to relax since I was a little nervous as to what “stem cell” was. After the treatment, it took a couple of weeks to really start feeling better. It has now been three months and I am NOT in pain anymore. I am the happiest that I didn’t do the surgery and went with Dr. Lans. It will still take a little more time for my ankle to be back to normal but I am well on my way. THANK YOU DR. LANS

  • Across the 16+ years during which Dr. Lans provided primary care as well as specific treatments for me, I came to understand, respect and appreciate what I am certain is only a small part of the considerable breadth and scope he brings to the task. Where medicine is a blend of science and art, he brings the best in command of broad knowledge and distills practical wisdom and insight from clinical experience, and from my observation, his thinking and judgment are not bound by convention or other potentially limiting factors.

  • It is rare to find a doctor these days who actually sits down and talks to you. What a refreshing experience!!

  • I went for years with undiagnosed symptoms and within two visits Dr. Lans had diagnosed the problem! Although having a chronic illness has a huge downside, he is open to trying alternative therapies and he is extremely respectful of every patient he sees. If you no longer trust Doctors or if you have been seen by abusive caregivers, give Dr. Lans a chance. He is the only reason I am as well as I am today.
