“…The first studies using the ovary-on-a-chip technology have shown promising results 652 supporting follicle development [211,212,263,264]. It has also been successfully applied to 653 monitor ovotoxicity induced by microcystins [263], study anti-cancer drugs effects on 654 ovarian follicles growth and function [265], and as a model for ovarian cancer [213, 266, 655 267] and a tool to characterize oocyte quality [268,269]. However, this approach is still in 656 its infancy, and it will surely be explored in the following years.…”

Considerable challenges in engineering the female reproductive tissue are the follicle's 25 unique architecture, the need to recapitulate the extracellular matrix, and tissue 26 vascularization. Over the years, various strategies have been developed for preserving 27 fertility in women diagnosed with cancer, such as embryo, oocyte, or ovarian tissue 28 cryopreservation. While autotransplantation of cryopreserved ovarian tissue is a viable 29 choice to restore fertility in prepubertal girls and women who need to begin chemo-or 30 radiotherapy soon after the cancer diagnosis, it is not suitable for all patients due to the risk 31 of having malignant cells present in the ovarian fragments in some types of cancer. Advances 32 in tissue engineering such as 3D printing and ovary-on-a-chip technologies have the 33 potential to be a translational strategy for precisely recapitulating normal tissue in terms of 34 physical structure, vascularization, and molecular and cellular spatial distribution. This 35 review first introduces the ovarian tissue structure, describes suitable properties of 36 biomaterials for ovarian tissue engineering, and highlights recent advances in tissue 37 engineering for developing an artificial ovary. 38 39 40 Keywords 41 Ovarian tissue engineering; follicle; in vitro culture; 3D printing; ovary-on-a-chip 42 157 9 Ovarian cells can be added to the isolated follicles to support their development 158 during in vitro culture or transplantation. These cells secrete autocrine/paracrine 159 factors involved in folliculogenesis [44], and some of them will be recruited by 160 growing follicles to differentiate into theca cells [48]. Moreover, to improve follicle 161 survival, one could play with the biomaterial used as a scaffold, its porosity, 162 mechanical strength, and bioactive sites, as well as the addition of hormones, growth 163 factors, etc. [8, 11, 49-53]. For instance, to enhance vascularization, follicles could be 164 encapsulated in biomaterials with sustained release of vascular endothelial growth 165 factor (VEGF) [54] or basic fibroblast growth factor (bFGF) [55]. 166 167 4 Development of follicle culture systems 168The 2D in vitro system has been routinely used for follicle' in vitro culture [56][57][58][59][60][61]. Several 169 approaches, such as multi-well plates, cell culture dishes, or coverslips coated by gels or ECM 170 proteins such as collagen, fibronectin, and laminin, have been used in this procedure [3, 33, 171 62]. When isolated follicles are attached to a 2D culture surface, the somatic cells migrate to 172 the bottom of the well, gradually losing their interaction with the oocyte, and consequently, 173 the follicle 3D structure is destroyed [7]. Indeed, 2D culture systems are different from in 174 vivo microenvironment conditions, where cells and tissues have complex connections with 709This study was supported by grants from the Fonds National de la Recherche Scientifique de 710 Belgique (the Excellence of Science (FNRS-EOS), number 30443682 (PhD scholarship 711 award...

“…This technology enabled genetic uniformity within livestock species, and provided an opportunity for breeders to select preferred traits (Sekhon 2012). Kempisty et al (2014) developed a microfluidic device to analyze the impact of follicle size on oocyte quality. The microfluidic device consisted of a silicon-glass sandwich with embedded glass optical fibers for the spectral analysis of pig oocytes.…”

Background: Microfluidics is of considerable importance in food and agricultural industries. Microfluidics processes low volumes of fluids in channels with extremely small dimensions of tens of micrometers. It enables the miniaturization of analytical devices and reductions in cost and turnaround times. This allows automation, high-throughput analysis, and processing in food and agricultural applications. Purpose: This review aims to provide information on the applications of microfluidics in the agro-food sector to overcome limitations posed by conventional technologies. Results: Microfluidics contributes to medical diagnosis, biological analysis, drug discovery, chemical synthesis, biotechnology, gene sequencing, and ecology. Recently, the applications of microfluidics in food and agricultural industries have increased. A few examples of these applications include food safety analysis, food processing, and animal production. This study examines the fundamentals of microfluidics including fabrication, control, applications, and future trends of microfluidics in the agro-food sector. Conclusions: Future research efforts should focus on developing a small portable platform with modules for fluid handling, sample preparation, and signal detection electronics.

“…This may be because light can more easily pass through the wider cytoplasmic area in front of it, and the less cytoplasmic transparency from the zona allows for detecting differences in light reflected and passed through the cytoplasm. 41,43,44 In optical systems, the maturity stage of an oocyte is determined based on its optical transmission properties 44 and even oocytes are categorized into different quality groups, such as good and bad groups based on optical features related to their morphological characteristics, 39 although there are currently no optical findings of oocytes that may be related to their developmental potential.…”
