Abstract
Mesenchymal stem cells are used in the treatment of many diseases, particularly in the repair of bone injuries. Algae with various medicinal applications are considered important natural resources. There is limited research on the effects of bioactive peptides from algae extraction on mesenchymal stem cells. In this study the impact of bioactive proteins, protein lysates and peptide fractions (<3, <30 and <50 kDa) isolated from two algae species, Spirulina platensis and Gracilaria gracilis on the proliferation and osteogenic differentiation of human amniotic mesenchymal stem cells (hAMSCs) was investigated. The proteins were extracted ant hydrolyzed with trypsin enzyme to create peptides, which were then separated by ultrafiltration. hAMSCs were exposed to different concentrations of bioactive compounds (100, 300, 500 and 700 µg/ml) for varying time periods. Cell proliferation was assessed using the with 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, and to evaluate differentiation into bone tissue, the amount of mineral deposition was measured with alizarin red staining, and alkaline phosphatase enzyme activity was determined using a colorimetric method. The expression of Runx2, Osteocalcin, and β-Catenin genes expression was analyzed using RT-qPCR on days 7, 14 and 21 post-treatment. The results indicated that the <3 kDa peptide fraction of S. platensis and G. gracilis had no cytotoxic effects, increased cell proliferation at a concentration of 300 μg/ml, and enhanced the expression of osteogenic marker genes, alkaline phosphatase enzyme a activity, and calcium deposition in the extracellular matrix. In general, fractions that show positive effects on hAMSC differentiation have the potential to treat bone defects and promote osteoregeneration.

Osteogenic differentiation of human amniotic mesenchymal stem cells by phycocyanin and phycoerythrin pigments isolated from Spirulina platensis and Gracilaria gracilis algae. Tissue Cell 2023; 85:102216. [PMID: 37774523 DOI: 10.1016/j.tice.2023.102216] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Revised: 08/17/2023] [Accepted: 09/09/2023] [Indexed: 10/01/2023]
Abstract
Bone regeneration is a multistep and regular physiological process that occurs normally in fracture repair and bone defects. However, some factors such as aging, particular diseases and some drugs prevent or slowdown bone natural healing. Cell therapy using stem cells and differentiation activating factors is an effective treatment method for bone regeneration triggering in unusual conditions. Therefore, in the present study the effect of phycocyanin and phycoerythrin pigments which isolated from Spirulina platensis and Gracilaria gracilis algae was investigate on osteogenic differentiation potency of human Amniotic Mesenchymal Stem Cells (hAMSCs). For this purpose, hAMSCs were exposed to 300, 500, and 700 µg/ml concentrations of phycocyanin and phycoerythrin pigments and then the cells viability was measured with MTT assay in 48 and 72 h after treatment. The osteo-differentiation level of cells was studied by measuring ALP activity using calorimetric method and Alizarin red staining for calcium deposition in 7 and 21 days after treatment. Also, total RNA of cells was extracted in different time periods and then cDNA synthesized with specific primers, and relative expression of Runx2, β-catenin and Osteocalcin genes were investigated using SYBR Green RT-qPCR technique. Osteogenic differentiation of hAMSCs that treated with pigments was confirmed by mineral deposits staining and increased level of ALP activity. Furthermore, these pigments elevated significantly the expression of osteogenic marker genes compared to control samples and caused hAMSCs to differentiate into osteoblast cells. According to these results, phycocyanin and phycoerythrin may suggest as suitable osteogenic supplements with low toxicity, low cost and high efficiency, although the molecular mechanism of its efficacy is not available yet.

Abstract
Marine environment has demonstrated to be an interesting source of compounds with uncommon and unique chemical features on which the molecular modeling and chemical synthesis of new drugs can be based with greater efficacy and specificity for the therapeutics. Cancer is a growing public health threat, and despite the advances in biomedical research and technology, there is an urgent need for the development of new anticancer drugs. In this field, it is estimated that more than 60% of commercially available anticancer drugs are natural biomimetic inspired. Among the marine organisms, algae have revealed to be one of the major sources of new compounds of marine origin, including those exhibiting antitumor and cytotoxic potential. These compounds demonstrated ability to mediate specific inhibitory activities on a number of key cellular processes, including apoptosis pathways, angiogenesis, migration and invasion, in both in vitro and in vivo models, revealing their potential to be used as anticancer drugs. This review will focus on the bioactive molecules from algae with antitumor potential, from their origin to their potential uses, with special emphasis to the alga Sphaerococcus coronopifolius as a producer of cytotoxic compounds.
