“…Finally, it has been shown that Sr uptake by T. chui cells is much higher than that of microalgae that do not form micropearls. T. chui cells significantly decreased Sr concentrations in the culture media, supporting the idea of using micropearl‐forming Chlorodendrophyceae species as potential candidates to develop new remediation techniques to treat radioactive 90 Sr contamination (Møller & Mousseau, 2006; Pathak & Gupta, 2020; Vakulovsky et al, 1994). Alternatively, micropearl‐forming Chlorodendrophyceae could be used to reduce natural Sr levels in drinking water (Agency for Toxic Substances and Disease Registry, 2004; Health Canada, 2019).…”

Strontium-rich micropearls (intracellular inclusions of amorphous calcium carbonate) have been observed in several species of green microalgae within the class Chlorodendrophyceae, suggesting the potential use of these organisms for 90 Sr bioremediation purposes. However, very little is known about the micropearl formation process and the Ca and Sr uptake dynamics of these microalgae. To better understand this phenomenon, we investigated, through laboratory cultures, the behaviour of two species within the class Chorodendrophyceae: Tetraselmis chui, forming micropearls, and T. marina, not forming micropearls. We show that T. chui growth and micropearl formation requires available Ca in the culture medium, and that the addition of dissolved Sr can partially replace the function of Ca in cells. On the other hand, T. marina can grow without added Ca and Sr, probably due to its inability to form micropearls. T. chui cells show a high Ca and Sr uptake, significantly decreasing the concentration of both elements in the culture medium. Strontium is incorporated in micropearls in a short period of time, suggesting that micropearl formation is, most likely, a fast process that only takes a few hours. In addition, we show that micropearls equally distribute between daughter cells during cell division.

“…On the earth's surface, Ca and Mg are in significant abundance (2.5% and 3.6%, respectively), while the remaining alkaline metals, Be, Ba, and Ra, are not in abundance (0.001%, 0.025%, and 0.05%, respectively). 23 Due to their high reactivity, alkaline earth metals do not exist in the form of simple substances and are usually present in sulfate, carbonate, hydroxide, and silicate forms with various uses and chemical characteristics. However, each alkaline earth metal element is present in the human body with various concentrations and properties.…”

Alkaline earth metals for osteogenic scaffolds: From mechanisms to applications

et al. 2023

Regeneration of bone defects is a significant challenge today. As alternative approaches to the autologous bone, scaffold materials have remarkable features in treating bone defects; however, the various properties of current scaffold materials still fall short of expectations. Due to the osteogenic capability of alkaline earth metals, their application in scaffold materials has become an effective approach to improving their properties. Furthermore, numerous studies have shown that combining alkaline earth metals leads to better osteogenic properties than applying them alone. In this review, the physicochemical and physiological characteristics of alkaline earth metals are introduced, mainly focusing on their mechanisms and applications in osteogenesis, especially magnesium (Mg), calcium (Ca), strontium (Sr), and barium (Ba). Furthermore, this review highlights the possible cross‐talk between pathways when alkaline earth metals are combined. Finally, some of the current drawbacks of scaffold materials are enumerated, such as the high corrosion rate of Mg scaffolds and defects in the mechanical properties of Ca scaffolds. Moreover, a brief perspective is also provided regarding future directions in this field. It is worth exploring that whether the levels of alkaline earth metals in newly regenerated bone differs from those in normal bone. The ideal ratio of each element in the bone tissue engineering scaffolds or the optimal concentration of each elemental ion in the created osteogenic environment still needs further exploration. The review not only summarizes the research developments in osteogenesis but also offers a direction for developing new scaffold materials.

“…The stable and radioactive Sr isotopes act identically in most physical, chemical and biological processes (Nedobukh, Semenishchev, 2020). In addition, due to similar characteristics of Sr with calcium (Ca), it enters bodies of organisms via accumulation onto the tissues and bones (Pathak et al, 2020).…”

“…Recently, researchers particularly have focused their interests on Sr found in soil-groundwater systems (Pathak et al, 2020;Sharma, 2020), since it is highly reactive , and in aqueous solution it can be bioavailable (Chatterjee et al, 2020;Ilyas et al, 2020).…”
