Modified Pfirrmann score of 1 must contain a contained protrusion and/or annular tear on MRI 4. Modic Grade I or II changes or no change on MRI 5. Maintained intervertebral disc heights of at least 50% on MRI. 6. Discography, if not performed within the last 6 months prior to informed consent date, has to be performed if more than one degenerative disc is identified by MRI, and the symptomatic disc cannot be otherwise reasonably determined 7. If more than one degenerative disc is identified by MRI, no disc shall demonstrate greater degenerative change than the symptomatic disc or contain a protrusion greater than 5mm 3. Aged ≥18 years of age at the time of consent 4. Willing and able to provide written informed consent 5. No evidence of contraindications to the procedure such as pregnancy, active infection, bleeding disorder, or metastatic cancer Subject Exclusion Criteria: A subject is not eligible to participate if any of the following criteria are met: 1. Spinal Deformity (Scoliosis greater than or equal to 20 degrees, spondylolysis, clinically or radiographically significant retrolisthesis or spondylolisthesis) detected on MRI or plain film radiographic assessment 2. Disc extrusions, sequestered fragments, facet cysts, or greater than moderate spinal stenosis on MRI. 3. Presence of a Grade V annular fissure observed within the index disc level during discography in a subject for whom provocation discography has been performed 4. Intervertebral disc with radiographic evidence of Modified Pfirrmann Grade 8 or greater 5. Any bleeding disorder, intrinsic or extrinsic 6. Required anticoagulation (with either antiplatelet agents or antithrombotics) that cannot be interrupted for harvest and injection procedures 7. Platelet count less than or equal to 100,000 8. International Normalized Ratio (INR) greater than or equal to 1.5 9. Extreme obesity, as defined by NIH Clinical Guidelines Body Mass Index (BMI greater than or equal to 40) 10. Clinically relevant instability on flexion-extension as determined by the investigator by overlaying films (flexion \& extension films) 11. Has undergone any previous lumbosacral spine surgery (e.g. discectomy, laminectomy, foraminotomy, fusion, intradiscal electrothermal therapy, intradiscal radiofrequency thermocoagulation.), ablation of lumbar basiverterbral nerve or therapeutic percutaneous disc intervention 12. Have any acute or chronic lumbosacral spine fracture 13. Have a history of lumbosacral epidural steroid injections within 1 month prior to informed consent date. 14. Planned/expected use of systemic nonsteroidal anti-inflammatory drugs (NSAIDs) within 72 hours prior to study treatment. 15. Have a known history of hypersensitivity or anaphylactic reaction to dimethyl sulfoxide (DMSO) 16. Active significant non lumbosacral spinal orthopedic pain generators including, not limited to arthritic hip and/or knee, cervical disc disease 17. More widespread and ill-defined myofascial pain 18. Have had treatment with any cellular or biological investigational therapy or device within 6 months of informed consent date and/or plans to participate in any other autologous or allogeneic stem cell/progenitor cell therapy trial during the 2 year follow-up period 19. Have been a recipient of any lumbosacral intervertebral disc injection for therapeutic purposes 20. Are transient or has been treated in the last 6 months before enrollment for alcohol and/or drug abuse in an inpatient substance abuse program 21. Apparent ongoing and poorly controlled psychological or somatic disease that may impact treatment outcomes 22. Social, familial, or geographical hindrances to compliance with the study protocol or the informed consent process 23. Known autoimmune disease with primary impact on the musculoskeletal and/or neurological systems (e.g., systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis, Sjogren's syndrome, myasthenia gravis, polymyositis/dermatomyositis, Guillain-Barre syndrome, autoimmune vasculitis) 24. Required chronic immunosuppression 25. Positive hepatitis C virus (HCV) antibody test 26. Positive human immunodeficiency virus (HIV) Antigen/Antibody (Ag/Ab) Combo test 27. Pregnant or lactating women 28. Women of childbearing potential not protected by a highly effective method of birth control. Highly effective methods of contraception \[defined as those, alone or in combination, that result in a low (\<1%) failure rate\] include, but are not limited to, combined (estrogen- and progestogen-containing) hormonal contraception associated with inhibition of ovulation (either oral, intravaginal, transdermal or injectable), progestogen-only hormonal contraception associated with inhibition of ovulation (either oral, injectable or implantable), intrauterine device, intrauterine hormone-releasing system, bilateral tubal occlusion, vasectomized partner, sexual abstinence, or a double-barrier method (i.e., male condom combined with diaphragm with spermicide). The investigator is responsible for review of medical history, contraception history, menstrual history and recent sexual activity to decrease the risk of including a woman with an undetected early pregnancy. Additionally, the investigator is responsible for determining if, in the investigator's judgment, a woman's planned contraceptive method (including an assessment of her reliability for consistent use of this method) meets the protocol requirement of "highly effective." 29. Hematology and chemistry values including, but not limited to: 1. Total bilirubin level 1.5 times institutional upper limit of normal (ULN) 2. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) 2 x ULN 3. Absolute neutrophil count (ANC) \< 1000/mm3 4. Hemoglobin less than or equal to 10 g/dL 5. Creatinine clearance use calculated clearance (Cockcroft-Gault equation) of less than or equal to 50 mL/min 6. Other labs deemed clinically significant which, in the opinion of the investigator, might influence the subject's health or safety during the trial. 30. Have any other active medical conditions, medical or psychiatric illness which, in the opinion of the Investigator, would preclude adequate evaluation of the safety and efficacy of the study or put the participant at risk 31. Inability to comply with the requirements of the study protocol 32. Actively on workers compensation or no-fault case for this complaint or any other active case or litigation pertaining to their lumbosacral pain. 33. History of drug or alcohol abuse or documented history of noncompliance with controlled substances that, in the investigator's opinion, could interfere with adequate evaluation of the study drug's safety or efficacy or otherwise make the subject unsuitable for the study. 34. History of regular, long term, daily opioid drug use (greater than or equal to 30 MME)
