Resumo: | The present research aims to evaluate in vivo a cellular compound for bone tissue engineering containing mesenchymal stem cells of adipose origin (mASCs), concentrated supernatant, hybrid hyaluronic acid (AH-HLW) and hydroxyapatite/?-tricalcium-phosphate (HP/?TCP) as bone substitute. Critical bone defects (144) were performed in the femoral region with 2 mm in diameter (two defects per femur) in 36 Lewis rats. The grafting treatments were divided as follows: I- negative control/only the defect (CT); II- mASCs (OST); III- mASCs + AH (AC); IV- HP/?TCP (H); V- Supernatant (SP); VI- AH-HLW + mASCs+ HP/?TCP (ACH). After 15 and 30 days the rats were euthanized and the defects used for microtomographic (micro-CT) and histomorphometric, RT-PCR (Real-Time Polymerase Chain Reaction) and ELISA (Enzyme- Linked Immunosorbent Assay) analysis. The results for the micro-CT tests reagarding bone volume (%) had greater values for (ACH), (H) and (SP) groups. Regarding histomorphometry, (CT) group had greater area of regenerated bone tissue differing from (ACH) group for 15 days, not presenting statistical differences among all groups for the 30 days period. Regarding RT-PCR, type I collagen (col1A) and osteopontin (OP) presented more expressive values for group (SP) in 15 days. For group (H), the BMP-4 was more expressive and for (OST) group OP and BMP-2 for 30 days. Cytokines were evaluated by quantification in the supernatant and greater expression was observed for groups (ACH) e (H) compared to others. Results indicated that group (ACH) secreted more VEGF, FGF and IGF-1 cytokines in 30-days period. The application of bone grafting techniques using acellular compounds derived from the mASC supernatant culture, and compounds with cells associated with bone substitutes or osteoconductive matrices promising results in tissue engineering. |

Foram realizados 144 defeitos ?sseos cr?ticos (DOC) na regi?o femoral de 36 ratos Lewis medindo 2 mm de di?metro (dois defeitos por f?mur). Os compostos para enxertia realizados foram divididos em grupos: I- controle (negativo), tendo apenas o defeito (CT); II- concentrado de meio de cultura (SP); III- C?lulas mesenquimais adipog?nicas (mASCs) diferenciadas em osteoblastos (OST); IV- mASCs + ?cido hialur?nico (AH) (AC); V- (HP/?-TCP) (H); VI- HA-HLW + mASCs + (HP/?-TCP) (ACH). Ap?s 15 e 30 dias os ratos sofreram eutan?sia e os defeitos foram analisados por microtomografia computadorizada (micro-CT), histomorfometria, RT-PCR (Rea??o em cadeia da Polimerase em tempo Real) e ELISA (ensaio de imunoabsor??o enzim?tica). Os resultados para o teste de micro-CT do percentual de volume de tecido ?sseo neoformado sugeriram maior volume para o grupo (ACH) e (H), diferindo dos demais (p<0,05). Na histomorfometria o grupo (CT) apresentou maiores valores diferindo estatisticamente do grupo (ACH) (p<0,05) para 15 dias e n?o houve diferen?as entre os grupos no percentual de ?rea de tecido ?sseo regenerado no per?odo de 30 dias. No RT-PCR, para o tempo de 15 dias, o grupo (SP) teve valores mais expressivos de colagenase I (Col1A) e osteopontina (OP). Para 30 dias o grupo H teve maior express?o de BMP-4, o grupo (OST) de OP e BMP-2 em rela??o aos outros grupos. No ELISA foram encontradas as maiores express?es dos fatores de crescimento nos grupos (ACH) e (H) em compara??o aos outros. Os fatores de crescimento IGF-1, VEGF e FGF apresentaram maior express?o no grupo (ACH) para 30 dias. A aplica??o de t?cnicas de enxertia utilizando tanto compostos acelulares derivados do meio de cultura das mASCs, quanto compostos com a presen?a de c?lulas associados a substitutos ?sseos ou matrizes osteocondutoras apresentou resultados promissores na neoforma??o ?ssea.Submitted by PPG Odontologia (odontologia-pg@pucrs.br) on 2022-08-29T19:33:21Z No. of bitstreams: 1 ROBERTA_LIMEIRA_FULGINITI_TES.pdf: 2464519 bytes, checksum: 302078a25cf937a193b459bd49173019 (MD5)Approved for entry into archive by Sheila Dias (sheila.dias@pucrs.br) on 2022-09-05T15:06:21Z (GMT) No. of bitstreams: 1 ROBERTA_LIMEIRA_FULGINITI_TES.pdf: 2464519 bytes, checksum: 302078a25cf937a193b459bd49173019 (MD5)Made available in DSpace on 2022-09-05T15:19:22Z (GMT).

The present research aims to evaluate in vivo a cellular compound for bone tissue engineering containing mesenchymal stem cells of adipose origin (mASCs), concentrated supernatant, hybrid hyaluronic acid (AH-HLW) and hydroxyapatite/?-tricalcium-phosphate (HP/?TCP) as bone substitute. Critical bone defects (144) were performed in the femoral region with 2 mm in diameter (two defects per femur) in 36 Lewis rats. The grafting treatments were divided as follows: I- negative control/only the defect (CT); II- mASCs (OST); III- mASCs + AH (AC); IV- HP/?TCP (H); V- Supernatant (SP); VI- AH-HLW + mASCs+ HP/?TCP (ACH). After 15 and 30 days the rats were euthanized and the defects used for microtomographic (micro-CT) and histomorphometric, RT-PCR (Real-Time Polymerase Chain Reaction) and ELISA (Enzyme- Linked Immunosorbent Assay) analysis. The results for the micro-CT tests reagarding bone volume (%) had greater values for (ACH), (H) and (SP) groups. Regarding histomorphometry, (CT) group had greater area of regenerated bone tissue differing from (ACH) group for 15 days, not presenting statistical differences among all groups for the 30 days period. Regarding RT-PCR, type I collagen (col1A) and osteopontin (OP) presented more expressive values for group (SP) in 15 days. For group (H), the BMP-4 was more expressive and for (OST) group OP and BMP-2 for 30 days. Cytokines were evaluated by quantification in the supernatant and greater expression was observed for groups (ACH) e (H) compared to others. Results indicated that group (ACH) secreted more VEGF, FGF and IGF-1 cytokines in 30-days period. The application of bone grafting techniques using acellular compounds derived from the mASC supernatant culture, and compounds with cells associated with bone substitutes or osteoconductive matrices promising results in tissue engineering. |
