3D細胞培養及組織工程用生物合成水凝膠(hydrogel)
Ferentis獨特的生物合成組織基質技術在細胞培養和組織工程上有著非常廣汎的應用。Ferentis結合了現代聚合物科學和細胞生物學的技術研發出了基於細胞外基質的專有水凝膠配方。根據不同的實驗需求我們可以提供不同配方的水凝膠,其中包括基於膠原蛋白的水凝膠以及基於仿膠原肽(CMP:collagen-mimetic-peptide)的水凝膠。

Ferentis水凝膠的特點
●高度交叉鏈接的水凝膠的自然3D構造 (CMP) ●化學及物理特性有充分的研究(CMP) ●純生物合成,無動物來源(CMP) ●在微細加工下不會變形 ●便於處理和移動 ●便於顯微鏡解析的透明度 ●支持人類角膜上皮細胞(HCEC)、皮膚成纖維細胞及角質形成細胞、星型膠質細胞及小膠質細胞的增殖 ●支持神經細胞的分化 ●支持腦組織切片的培養
水凝膠選擇概覽
膠原蛋白是細胞外基質的主要成份,在組織成長和維持結構完整性上有著關鍵性的作用。Ferentis的產品主要由兩個基本的原料組成:豬膠原蛋白及與聚乙二醇結合的合成仿膠原肽。

In Vitro產品–細胞培養用自我組裝肽水凝膠
Ferentis提供許多可隨即使用的產品,包括多種直徑的multiwell inserts、可定制的水凝膠板、可定制的Kit、甚至是器官模型支架(例如眼角膜)。
因為交叉鏈接水凝膠在製成後可以保持形狀,定制時可以指定微型Moulding或是微型Patterning。
同時因為水凝膠是根據自我組成的肽的納米纖維構造組成,我們可以通過修改配方和肽序列來滿足不同細胞的需求。當定制時我們會很樂意幫助您設定最適合您的實驗的水凝膠。

Multiwell Inserts
這是自我組裝仿膠原肽和豬膠原蛋白水凝膠的盤。水凝膠的剛度、表面活性分子、表面模倣、表面形塑等都可以直接影響并控制細胞附著程度、成長、增生、以及相互作用。

產品須知:
我們也能製作其他規格或是滿足不同的包裝需求
大小或是容量都能根據使用者的需求來變更,
詳細請向本公司Tokyo Future Style確認
組織切片培養Kit
Ferentis的組織切片培養Kit是由置於專門的塑膠支架上的生物兼容disk而組成。這個設計具有優秀的通風并且可供定期交換培養基和代謝物。在實驗結束後,將有組織切片的水凝膠轉移到小容量的multi-well plate來進行後續的免疫組化等實驗也相當方便。另外,在進行冷凍保存或是石蠟包裹的時候,水凝膠都能保護組織不受傷害。在水凝膠上的組織能夠通過顯微鏡直接觀察,也可以直接對應電氣生理學的測試。

水凝膠的應用:
3D細胞培養
Primary neurons and glia from developing rat cerebellum on Ferentis collagen mimetic peptide hydrogel (left) and tissue culture plastic.
Neurons are immunostained yellow for microtubule associated protein 2, astrocytes are stained red for glial fibrillary acidic protein, microglia are marked green with fluorescent isolectin conjugate, and blue are all nuclei stained with a DNR binding dye Hoechst33342. The small images below distinguish neurons from astrocytes that merge to orange structures when are localized close together. The cells form 3D spheroids on Ferentis collagen mimetic peptide (CMP) hydrogel that communicate with neurite fibers supported by co-localizedd astrocytes. The spherical bodies are actively shaped by microglia which are selectively removing synapses, neurites and entire neurons. This mimics the in vivo tissue formation process. The same cells make a more static monolayer on cell culture plastic surfaces with fewer neurites, decreased contacts between astrocytes and neurons, and visibly flattened microglia. Cells were visualized under a laser scanning microscope Zeiss Axio Observer LSM700.。
細胞接著
Primary neuronal-glial cells on collagen mimetic peptide (CMP, left image) and CMP with hyaluronic acid (HA), right, after 5 days in culture.
CMP induced spherical neuronal-astrocyte formation surrounded by microglia, and introduction of HA made cells adhere to the hydrogel surface. Phase contrast images made by Olympus IX71S1F-3 microscope.
細胞增生
Human corneal epithelial cell (HCEC) attachment and proliferation on collagen mimetic peptide hydrogel.
Left image – 24h after plating, right image – after 5 days in vitro. The same cells did not attach to negative control samples made from PEG hydrogel. GFP-tagged cells were visualized by fluorescent microscope Zeiss AxioVert A1.
神經突生長
Introduction of IKVAV peptide sequence from laminin into CMP structure induced significant neuritogenesis (left) compared to neurons on plastic surface (upper right) and porcine collagen (lower right).
Neurons are immunostained yellow for microtubule associated protein 2 and visualized under a laser scanning microscope Zeiss Axio Observer LSM700.
In Vitro 應用例
In vitro 眼角膜 model
Human corneal epithelial cells cultured on hydrogel matrices in air-liquid interface.
Human corneal epithelial cells were seeded on collagen mimetic peptide (CMP) based hydrogel matrix, lifted to air-liquid interface and cultured for 21 days. The picture of multilayered culture (left panel) was taken prior to paraffin embedding, slicing and H&E staining (right panel).
in vitro 皮膚 model
Human skin keratinocytes cultured on hydrogel matrices in air-liquid interface.
Human skin keratinocytes were seeded on collagen mimetic peptide (CMP) based hydrogel matrix, lifted to air-liquid interface and cultured for 21 days. The picture of the multilayered culture (left panel) was taken prior to paraffin embedding, slicing and Hematoxilin&Eosin staining. Multilayer stratification is visible in CMP-based culture with a basal level composed of uniform cuboidal cells and an upper layer composed of flat, compacted and cornified cells.
