Effect of Human Umbilical Cord Mesenchymal Stem Cell Transplantation in a Rat Model of Preeclampsia.
OBJECTIVE: To test the effects of human umbilical cord mesenchymal stem cell (HU-MSC) transplantation on reversing preeclampsia (PE) symptoms in a lipopolysaccharide (LPS)-induced rat PE model.
METHODS: Human umbilical cord MSCs were detected, isolated, and cultured. Human umbilical cord MSC transplantation was conducted. Expressions of inflammatory cytokines in serum and placental tissue were measured by enzyme-linked immunosorbent assay. Changes in inflammatory cytokines, peroxisome proliferator-activated receptor γ (PPARγ), laminin receptor 1 (LR1), matrix metalloproteinase (MMP) 2, and MMP-9 messenger RNA (mRNA) levels in placental tissue were recorded by quantitative real-time polymerase chain reaction. Immunohistochemistry and Western blotting were performed for PPARγ detection.
RESULTS: The LPS group exhibited increased blood pressure and proteinuria and decreased fetal weight compared to the normal pregnancy (NP) group (all P < .05). The LPS + MSC group presented lowered blood pressure and higher fetal weight than the LPS group (P < .05). The levels of interferon γ, tumor necrosis factor α (TNF-α), interleukin (IL) 1β, IL-6, IL-8, IL-12, and intercellular adhesion molecule 1 (ICAM-1) increased and the levels of IL-4 and IL-10 levels decreased in the LPS group compared to the NP group (all P < .05). Tumor necrosis factor α, IL-6, IL-12, and ICAM-1 levels decreased and IL-10 level increased in the LPS + MSC group compared to the LPS group (all P < .05). The LPS-MSC group showed lower mRNA expressions of TNF-α, IL-6, MMP-2, MMP-9, and ICAM-1 and higher mRNA expressions of IL-10, PPARγ, and LR1 than the LPS group (all P < .05).
CONCLUSION: In summary, HU-MSC transplantation may be extremely beneficial for PE therapy.

I don’t see any info on neuropathy treatment . Is that an option?
Stem Cell Therapy for Neuropathic Pain: New Findings Show Promise
Animal studies demonstrate effectiveness
Stem cell research at Cleveland Clinic could pave the way for an entirely new approach to chronic pain treatment that reduces medicine’s current reliance on opioid therapy for intractable pain. The modality also shows promise as a tool to reverse opioid tolerance (OT) and opioid-induced hyperalgesia (OIH), particularly problematic side effects of opioid therapy. Jianguo Cheng, MD, PhD, and his colleagues at Cleveland Clinic have developed patented methods of attenuating opioid tolerance.
Animal studies by Dr. Cheng and his colleagues have demonstrated the effectiveness of mesenchymal stem cell (MSC) transplantation in reducing hyperalgesia due to nerve injury. The group’s work has shown MSC transplantation’s effectiveness in reducing pain induced by sciatic nerve injury in rats and mice. MSC transplantation significantly reduced pain sensitivity evaluated by foot withdrawal thresholds in animals in response to thermal or mechanical stimulation. These cells produced immune modulatory and anti-inflammatory effects, promoted sensory nerve repair, and showed strong analgesic properties that could provide a safer and more effective alternative to current treatment modalities, in the management of neuropathic pain, says Dr. Cheng, Professor of Anesthesiology and Director of the Cleveland Clinic Multidisciplinary Pain Medicine Fellowship Program.
Pain medicine researchers are searching for an alternative to opioid therapy because neuropathic pain often does not respond to morphine and other opioids. Opioid analgesics can also lead to a variety of complications, ranging from itching and constipation to dependence, addiction, respiratory depression and death.
About 30 percent of neuropathy cases are caused by nerve damage associated with diabetes. However, hundreds of diseases are linked to neuropathic pain. Sources of neuropathic pain include alcoholism, amputation (which can result in phantom pain), some chemotherapy drugs (for example, Cisplatin®, Paclitaxel®, Vincristine®), radiation therapy, complex regional pain syndrome type II, trigeminal neuralgia, shingles, spinal stenosis, and central nervous system disorders, such as Parkinson disease and multiple sclerosis.
Recent research by Dr. Cheng and his group has yielded new discoveries that bode well for MSC transplantation as a potential future treatment modality. One investigation compared the analgesic effects of MSC derived from bone marrow with MSC derived from adipose tissue. Adipose-derived cells were found to be as efficacious as bone marrow-derived cells in reducing neuropathic pain in rats. The finding suggests that stem cell therapy could offer a practical option because stem cells from adipose tissue are relatively easy to obtain.
Recent investigations by Dr. Cheng and his colleagues comparing the analgesic effectiveness of intrathecal versus intravenous methods of MSC transplantation show both methods to be equally effective. The finding has important implications because intravenous transplantation of MSC could offer a safer and more expeditious route of delivery than intrathecal transplantation.
“We originally thought that stem cells would have to be introduced intrathecally in order to reduce pain, and that stem cells introduced intravenously would pass through the lungs and fail to produce analgesia,” says Dr. Cheng. “The finding that intravenous transplantation is as effective as intrathecal transplantation is encouraging.”
Dr. Cheng’s group has also discovered that MSCs can be found in the area surrounding the injured nerve following MSC transplantation. “For reasons we do not yet fully understand, these cells have the ability to migrate to the injury site to promote repair of the injured nerve fibers,” Dr. Cheng says. “The cells can sense the injury’s location and travel to it.”
Although many questions must be answered before it can be known whether stem cell therapy is safe and effective for humans, some small patient studies show potential, Dr. Cheng says. According to one observational study in Australia, MSC transplantation reduced pain in patients suffering from trigeminal neuralgia, a particularly difficult condition to treat. “Though the findings are preliminary, the study provides some evidence that what we have learned in the laboratory can be translated to clinical use,” Dr. Cheng says.
Dr. Cheng’s team has achieved analgesia with MSC transplantation from rats to mice, providing early evidence that stem cells’ anti-inflammatory and immuno-modulatory properties can be transferred between species. An important pre-clinical study will be to see whether the transplantation of human stem cells to animals also can produce analgesic and anti-tolerance effects, Dr. Cheng says.
Dr. Cheng’s team presented research at the 2016 annual meeting of the American Academy of Pain Medicine showing MSC’s potential to reverse opioid tolerance and opioid-induced hyperalgesia, problems that can compromise the safety and efficacy of opioid therapy. Intravenous transplantation of bone marrow-derived MSC significantly attenuated OT and OIH in animals whether the transplantation was performed seven days before or 14 days after the initiation of daily morphine injections. These data demonstrate that MSC transplantation can not only prevent the development of OT and OIH but can also reverse it.
Hi, Dr.Riordan, I much appreciated your seminar on YouTube, such as the eye opener about mom’s gaining health from each baby they carry.. It sorta evens out the playing field, since men have more ECW plus hormones which many women don’t have. I recently had both an MRI & PedCat done on my right foot. I suffer from pain off the charts. Actually from both my feet AND systemically. I.E. degenerative and dislocated joints, varicose veins, Plantar Fasciitis, posterior tibial tendinitis, Excruciating neuropathy, arch cramps, ankle pain, bunions, hallux valgus, pes cavus, calcifications…you name it. I am confused as to the best course of action. I.E. why not cord blood MSCs? Why amniotic? Also, who says I even have sufficient MSCs in my body at this stage of the game? Please, how I wish somebody could help me. I’ve already been taken for a ride way too much by the rotten Rotten system c/o Bush & ilk.
