Mesenchymal stem cells (MSCs), first described in human bone marrow, are emerging as promising cell-based therapeutics for a wide range of diseases (Caplan and Correa, 2011). MSCs have been isolated from various organs in the body, and synovial MSCs were first reported by De Bari et al. (2001). We previously reported that synovial MSCs have superior proliferation and chondrogenic potentials as compared to bone marrow-, muscle-, and adipose- derived MSCs in humans (Sakaguchi et al., 2005) and rats (Yoshimura et al., 2007). In addition, administration of synovial MSCs for osteochondral defect promoted cartilage regeneration in a rabbit (Koga et al., 2008) and a pig model (Nakamura et al., 2012). In 2008, we started a clinical trial in human and obtained satisfactory results of symptoms and regenerated cartilage by Magnetic Resonance Imaging (Sekiya et al., 2015). We have also engaged in multiple research lines using synovial MSCs for meniscus regeneration in rats (Horie et al., 2009; Horie et al., 2012; Katagiri et al., 2013; Okuno et al., 2014; Ozeki et al., 2015). In this article, we demonstrated how to harvest the synovium including infrapatellar fat pad from a rat knee joint, and to describe the technique of isolation and culture of rat synovial MSCs.

Keywords: Synovium (滑膜), Mesenchymal stem cells (间充质干细胞), Rat (老鼠)

  1. Preparation of the surgery (10 min)
    1. Sacrifice a rat by delivering CO2 in a vinyl bag.
    2. Remove the hair around the knee joints, and sterile clean the legs with 70% ethanol (Figure 1D).
    3. Put the rat on the styrene foam, and cover the sterile sheet on the rat, keeping the right leg out of the hole. Stabilize the ankle with clip on the styrene foam (Figure 1E).

  2. Harvesting the synovium from the knee joint (Video 1) (10 min for both knee joints)
    1. Expose the patellar tendon with straight skin incision.
    2. Cut the patellar tendon transversely, and peel the tendon upward and downward to expose the infrapatellar fat pad.
    3. Separate the infrapatellar fat pad from the femur and tibia.
    4. Put the synovium into PBS in a Falcon tube.

  3. Isolation and culture of synovial MSCs
    1. Mince the synovium with a scalpel into 2-3 mm pieces.
    2. Put the minced synovium in collagenase solution.
    3. Place the tube in the incubator for 2-3 h. Shake it 2-3 times per hour.
    4. Filter the digested solution through a cell strainer.
    5. Centrifuge the tube at 580 x g for 5 min.
    6. Remove the supernatant, and plate the cells on the 56.7 cm2 dish (about 1,000 cells/ cm2).
    7. Change the medium twice a week and culture for 2 weeks with α-MEM containing 10% FBS with antibiotics.

Representative data

We can usually harvest 1 x 104 cells from one synovium (Figure 2). After 2 weeks, we can obtain 5 x 105-1 x 106 MSCs from one dish. The cells are heterogenous, and we usually use these cells of passage 2-4 in the experiments. We reported these data in our previous reports (Yoshimura et al., 2007).

首先在人骨髓中描述的间充质干细胞(MSC)正在作为用于广泛疾病的有希望的基于细胞的治疗剂出现(Caplan和Correa,2011)。 MSC已经从体内各种器官中分离,并且滑膜MSCs首先由De Bari等人(2001)报道。我们先前报道了与人类骨髓,肌肉和脂肪来源的MSC(Sakaguchi等人,2005)和大鼠(Yoshimura等人,2005)相比,滑膜MSC具有更好的增殖和软骨形成潜能> et al。,2007)。此外,施用用于骨软骨缺损的滑膜MSC促进兔子中的软骨再生(Koga等人,2008)和猪模型(Nakamura等人,2012) 。在2008年,我们开始了人类的临床试验,并通过磁共振成像获得令人满意的症状和再生软骨的结果(Sekiya等人,2015)。我们还利用滑膜MSC在大鼠中进行了半月板再生的多个研究线(Horie等人,2009; Horie等人,2012; Katagiri等人al。,2013; Okuno等人,2014; Ozeki等人,2015)。在本文中,我们演示了如何从大鼠膝关节收获包括髌下脂肪垫的滑膜,并描述大鼠滑膜MSC的分离和培养技术。
