Low back pain is common and degenerated discs (DDs) are believed to be a major cause. In non-degenerated intervertebral (IVDs) presence of stem/progenitor cells was recently reported in different mammals (rabbit, rat, pig). Understanding processes disc degeneration regenerative mechanisms within DDs important. The aim the study examine local human if these cell populations could respond paracrine stimulation vitro. Tissue biopsies from IVD region (L3-S1) were collected 15 patients, age 34-69...

Low back pain is a major health issue and one main cause to this condition believed be intervertebral disc (IVD) degeneration. Stem cell therapy for degenerated discs using mesenchymal stromal cells (MSCs) has been suggested. The aim of the study was investigate presence distribution pattern autologous MSCs transplanted into IVDs in patients explanted posttransplantation. IVD tissues from four (41, 45, 47, 47 years age) participating clinical feasibility on MSC transplantation degenerative...

For evaluation of cell therapy strategies using human mesenchymal stem cells (hMSCs), it is important to be able trace transplanted and their distribution in tissues, for example, cartilage, over time. The aim the study was determine effects on viability, traceability, chondrogenic differentiation hMSCs after iron labeling with sucrose. were collected (seven donors, 13-57 years) from patients undergoing spinal surgery. Two subsets experiments performed. (1) Iron hMSCs: 1 mg/mL Venofer(®)...

Occurrence of malignancy in a thyroglossal duct cyst (TDC) children and adolescents is very rare, preoperative diagnosis challenge, appropriate management still debated. We report 19-year-old male patient referred for midline neck mass diagnosed as an atypical TDC after initial subsequent investigations. Ultrasound-guided fine-needle aspiration (FNA) the was diagnostic papillary thyroid carcinoma. Sistrunk procedure total thyroidectomy were performed. Histologic analysis confirmed presence...

For evaluation of cell therapy applications, it is interest to be able trace and observe cellular distribution the transplanted cells. The aim with study was examine viability, traceability, multilineage capability iron sucrose-labeled mesenchymal stem cells (MSCs) after transplantation into lapine intervertebral discs (IVDs). MSCs were collected from three human donors, age 31-50 years, IVDs 12 rabbits, 3 months. isolated bone marrow cultured using standard protocols. Iron sucrose labeling...

<h3>Purpose</h3> Degeneration of the intervertebral disc is considered to be central in pain pathogenesis patients suffering from chronic low back (LBP). In recent years, injection mesenchymal stromal cells (MSCs) into arrest or reverse degenerative process has been proposed as an alternative therapy. The aim present study was investigate feasibility using iron-labeled MSCs for intradiscal with long-standing LBP. <h3>Methods</h3> Ten (7 men, 3 women, mean age 40 range 26–53) LBP and...
