Encouraging but Unpredictable and Sporadic miraculous results are observed in patients with various neurodegenerative disorders ranging from
spinal cord injury,
motor neuron disease,
How it works-
Because of Chemokines secreted by Damaged tissue Neurotrophic Growth factors added along with stem cells
Blood-Brain Barrier :
Avoided using Intrathecal approach
Also made permeable by selective use of drugs
Because of presence of Endothelial Stem cell Population in Cocktail along with Platelets and Growth factors
Stem cell treatment induces angiogenesis, Predominantly responsible for tissue repair
Intravenous injection of MSCs after induced stroke resulted in augmented levels of endogenous VEGF as well as increased angiogenesis in transition zone
Secrete growth factors which Modulate the Locoregional Milieu :
• promote self-repair of residing tissue cells.
• reactivate dormant neurons
• Remyelination of Denuded Axons
Glial Cell-Line Derived Neurotrophic Factor (GDNF)
Brain-Derived Neurotrophic Factor (BDNF)
Nerve Growth Factor (NGF)
Vascular Endothelial Growth Factor(VEGF)
Hepatocyte Growth Factor (HGF)
Engraftment and Transdifferentiation
After homing and subsequent survival of MSCs, their differentiation into neurons and astrocytes, leading to enhanced neural function (The concept of plasticity of stem cells or transdifferentiation )
MSCs have also been shown to differentiate into neurons vivoand in vitro
Bone marrow derived MSCs differentiation into neural cells under appropriate stimuli
The Research behind the methodology
Intensive animal research and encouraging results from proof of concept studies support the concept
How it is done-
Patients are evaluated clinically, rdiologicaly by MRI,PETscans ,electrphysiologicaly by EEG,somatosensory evoked potentials
Patients advised to strictly avoid smoking, drug or alcohol consumption and have a positive life style
As a day care procedure 240 ml of Bone marrow and 100 ml of fat is aspirated and processed for stem cells isolation. 2 ml of stem cells processed as per GMP is injected either into
• Intra arterial (BBB)
• Intrathecal (CSF BRAIN BARRIER)
Intrathecal application of stem cells
Intralesional administration under fluoroscopic control
Intralesional administration under direct visualistaion limited exposure
Direct implantation during Open surgery
Need of aggresive physiotherapy & Rehabilitation
crucial for these neurons to make functional synapses

Vision improved in 40 %
Results vary between 40 -60 % depending on cause, duration of the disease, age of the patient.
In sub acute phase success rate exceeds up to 75 %.
Improvement in the visual acuity in (58 %) of eyes. It was marked, good and moderate in 20%, 22 %and 16% eyes, respective¬ly. Slight improvement was seen in 2 % of cases.
No eye showed fur¬ther deterioration of vision
(52%) showed improved vascularity of the disc, increased calibre of the re¬tinal arterioles and general improvement in the color of the peripheral fundus
47% was increase in the field of vision, both central and peripheral.
20% of them had no residual general¬ized peripheral field constriction
Multiple sclerosis -60 -80 million cells injected intrathecally and 60-80 million intravenously given 3 to 5 times.
*Treatment decreased tissue damage in the patients, and had the capacity to
completely suppress further tissue damage
*Clinical efficacy in disability score (MS functional rating scale (EDSS) scale. upto 65 % of patients showed MS functional rating scale (EDSS) scale by at least 2 degree.
*Total volume of lesions in the brain or spinal cord showed reduction up to 25 % in 40 % of patients (MRI)
* Cells tracked them with a paramagnetic material and visualize on MRI confirmed their presence in affected motor areas of the CNS gray matter, hence correlated indication clinical efficacy.
*Clinical effect remained sustained – no major relapse seen in 40 % till now (follow up period of 5 yrs)
