The Science of Mesenchymal Stem Cells and Regenerative Medicine – Arnold Caplan PhD (VIDEO Part 3)

In part 3, Professor Caplan discusses the science behind mesenchymal stem cells: sources of mesenchymal stem cells (MSCs), because all MSCs are pericytes one can find them in any tissue that has blood vessels, pericytes express markers of MSCs, frequency of pericytes in human tissue, most abundant source of pericytes is adipose (fat) tissue, adipose-derived stem cells, how MSCs are separated from fat, chemistries MSCs from different tissues are not the same, MSCs function at sites of injury, mesenchymal stem cell homing in mice, MSCs don’t make fat, they don’t make muscle. They come back as pericytes, and not all pericytes are MSCs.

The dual effect of MSCs on tumour growth and tumour angiogenesis

Michelle Kéramidas, Florence de Fraipont, Anastassia Karageorgis, Anaïck Moisan, Virginie Persoons, Marie-Jeanne Richard, Jean-Luc Coll and Claire Rome

Abstract (provisional)

Introduction

Understanding the multiple biological functions played by human mesenchymal stem cells (hMSCs) as well as their development as therapeutics in regenerative medicine or in cancer treatment are major fields of research. Indeed, it has been established that hMSCs play a central role in the pathogenesis and progression of tumours, but their impact on tumour growth remains controversial.

Our results suggest that hMSCs injection decreased solid tumour growth in mice and modified tumour vasculature, which confirms hMSCs could be interesting to use for the treatment of pre-established tumours.

Methods

In this study, we investigated the influence of hMSCs on the growth of pre-established tumours. We engrafted nude mice with luciferase-positive mouse adenocarcinoma cells (TSA-Luc+) to obtain subcutaneous or lung tumours. When tumour presence was confirmed by non-invasive bioluminescence imaging, hMSCs were injected into the periphery of the SC tumours or delivered by systemic intravenous injection in mice bearing either SC tumours or lung metastasis.

Results

Regardless of the tumour model and mode of hMSC injection, hMSC administration was always associated with decreased tumour growth due to an inhibition of tumour cell proliferation, likely resulting from deep modifications of the tumour angiogenesis. Indeed, we established that although hMSCs can induce the formation of new blood vessels in a non-tumoural cellulose sponge model in mice, they do not modify the overall amount of haemoglobin delivered into the SC tumours or lung metastasis. We observed that these tumour vessels were reduced in number but were longer.

Conclusions

Our results suggest that hMSCs injection decreased solid tumour growth in mice and modified tumour vasculature, which confirms hMSCs could be interesting to use for the treatment of pre-established tumours.

Autologous bone marrow-derived cell therapy combined with physical therapy induces functional improvement in chronic spinal cord injury patients

Cell Transplant. 2013 Feb 26. [Epub ahead of print]

El-Kheir WA, Gabr H, Awad MR, Ghannam O, Barakat Y, Farghali HA, Maadawi ZM, Ewes I, Sabaawy HE.

Abstract

Spinal cord injuries (SCI) cause sensory loss and motor paralysis and are treated with physical therapy, but most patients fail to recover due to limited neural regeneration. Here we describe a strategy in which treatment with autologous adherent bone marrow cells is combined with physical therapy to improve motor and sensory functions in early-stage chronic SCI patients

In a phase I/II controlled single-blind clinical trial (clinicaltrials.gov identifier: NCT00816803), 70 chronic cervical and thoracic SCI patients with injury durations of at least 6 months were treated with either intrathecal injection(s) of autologous adherent bone marrow cells combined with physical therapy, or with physical therapy alone. Patients were evaluated with clinical examinations, electrophysiological somatosensory evoked potential, MRI imaging, and functional independence measurements.

Chronic cervical and thoracic SCI patients treated with autologous adherent bone marrow cells combined with physical therapy showed functional improvements over patients in the control group treated with physical therapy alone, and there were no cell therapy-related side effects. At 18 months posttreatment, 23 of the 50 cell therapy-treated cases (46 percent) showed sustained improvement using the American Spinal Injury Association (ASIA) Impairment Scale (AIS). Compared to those patients with cervical injuries, a higher rate of functional improvement was achieved in thoracic SCI patients with shorter durations of injury and smaller cord lesions.

Therefore, when combined with physical therapy, autologous adherent bone marrow cell therapy appears to be a safe and promising therapy for patients with chronic spinal cord injuries. Randomized controlled multicenter trials are warranted.

Endometrial regenerative cells for treatment of heart failure: a new stem cell enters the clinic

Leo Bockeria, Vladimir Bogin, Olga Bockeria, Tatyana Le, Bagrat Alekyan, Erik J Woods, Amalia A Brown, Thomas E Ichim and Amit N Patel

Journal of Translational Medicine 2013, 11:56 doi:10.1186/1479-5876-11-56
Published: 5 March 2013

Heart failure is one of the key causes of morbidity and mortality world-wide. The recent findings that regeneration is possible in the heart have made stem cell therapeutics the Holy Grail of modern cardiovascular medicine. The success of cardiac regenerative therapies hinges on the combination of an effective allogeneic “off the shelf” cell product with a practical delivery system. In 2007 Medistem discovered the Endometrial Regenerative Cell (ERC), a new mesenchymal-like stem cell. Medistem and subsequently independent groups have demonstrated that ERC are superior to bone marrow mesenchymal stem cells (MSC), the most widely used stem cell source in development. ERC possess robust expansion capability (one donor can generate 20,000 patients doses), key growth factor production and high levels of angiogenic activity. ERC have been published in the peer reviewed literature to be significantly more effect at treating animal models of heart failure (Hida et al. Stem Cells 2008).Current methods of delivering stem cells into the heart suffer several limitations in addition to poor delivery efficiency. Surgical methods are highly invasive, and the classical catheter based techniques are limited by need for sophisticated cardiac mapping systems and risk of myocardial perforation. Medistem together with Dr. Amit Patel Director of Clinical Regenerative Medicine at University of Utah have developed a novel minimally invasive delivery method that has been demonstrated safe and effective for delivery of stem cells (Tuma et al. J Transl Med 2012). Medistem is evaluating the combination of ERC, together with our retrograde delivery procedure in a 60 heart failure patient, double blind, placebo controlled phase II trial. To date 17 patients have been dosed and preliminary analysis by the Data Safety Monitoring Board has allowed for trial continuation.The combined use of a novel “off the shelf” cell together with a minimally invasive 30 minute delivery method provides a potentially paradigm-shifting approach to cardiac regenerative therapy.

Allogeneic and autogolous stem cell therapy combined with physical rehabilitation: A case report on a chronically injured man with quadriplegia

Daniel Leonard in Panama

This is a research paper written by Rebecca Johnston, Daniel Leonard’s sister. She recently graduated from a Physical Therapy degree program, and wrote her Capstone paper about Daniel’s stem cell therapy treatment in Panama.

Daniel is presented anonymously in the paper, but Rebecca and Daniel have given their permission for this paper to be shared. Daniel’s ASIA scores (pre and post treatment) are in the appendix of this paper.

Allogeneic and autogolous stem cell therapy combined with physical rehabilitation: A case report on a chronically injured man with quadriplegia

Abstract:

Background and Purpose: Stem cell therapy for SCI is a potentially promising treatment with increasing interest. This case report describes the use of a particular stem cell therapy protocol for a patient with chronic spinal cord injury, and describes his subsequent therapy and outcomes.

Case Description: The patient is a 29-year-old male who is chronically injured from a cervical spinal injury, resulting in quadriplegia. The patient was treated with a combined protocol of intrathecal (IT) and intravaneous (IV) allogeneic MSC and CD34+ cells and IT autologous BMMC at 6 ½ years post-injury. The results track the patient’s physical therapy progress until 6 months following stem cell treatment.

Outcomes: Recovery of strength in upper extremity and lower extremity muscle groups was noted, along with a functional increase in grip strength, ability to ambulate with assistance, and a significant decrease in daily medications.
Discussion: This case supports further investigation into treatment of chronically injured SCI patients with stem cell therapy followed by physical therapy.

Manuscript word count: 4321

A few highlights:

“After the patient underwent the stem cell treatment and returned to outpatient physical therapy in his hometown clinic in the United States, his MMT scores were tested over the period of 5 months post-stem cell treatment…. The patient did not decrease in strength in any of the muscles tested, and experienced improvements in 6/13 upper extremity muscle groups, and 8/9 lower extremity muscle groups.”

“The patient also had an increase in grip strength. His grip strength was measured by his occupational therapist to be 5 lbs on the right and 25 lbs on the left at one month before his stem cell treatment. Six months later, his grip strength was measured to be 22 lbs on the right and 36 lbs on the left. The patient reported that this increase in grip strength led to functional improvements, such as being able to self-catheterize, which he was completely unable to do since his injury.”

“The patient was also able to ambulate for the first time in 5 years at approximately 4 months after finishing his treatment. He was able to ambulate in partial weight bearing with the harness and max assist of two for 40 yards at .5 MPH.”
